seamonkey: use vendored icu library

It has its own preferred version and it doesn't make much sense to
continue to chase incompatibilities and ABI breakage the latest point
release is introducing.

Should help the build.

www/seamonkey: Update 2.53.18.2

Changelog:
What's New in SeaMonkey 2.53.18.2

SeaMonkey 2.53.18.2 contains (among other changes) the following changes
relative to SeaMonkey 2.53.18.1:

  * Block set-cookie from multipart/x-mixed-replace with pref bug 1864385.
  * Check if WorkerRunnable::Run runs on top of
    WorkerThreadPrimaryRunnable::Run in a worker thread bug 1867982.
  * Process pairs in coord list in PolyArea bug 1878211.
  * Cherry-pick update to dav1d bug 1881093.
  * Land NSS NSS_3_90_2_RTM UPGRADE_NSS_RELEASE bug 1880562.
  * Fix DSN for send later bug 815638.
  * Catch webNavigation error during tab restore bug 1885748.

SeaMonkey 2.53.18.2 contains (among other changes) the following major changes
relative to SeaMonkey 2.49.5:

  * The Bookmarks Manager has switched its name to Library, and now also
    includes the History list. When History is invoked, the Library will be
    shown with the History list selected. The extensive modifications were
    needed because of Mozilla Gecko platform API changes.
  * Download Manager has been migrated to a new API. Although it looks pretty
    much the same as before, the search option is missing and some other minor
    details work differently. The previous downloads history is removed during
    the upgrade.
  * The layout panel was added to the CSS Grid tools.
  * TLS 1.3 is the default SSL version now.
  * Support for all NPAPI plugins like Flash, Java and Silverlight has been
    removed. For displaying pdf files in the browser you can use
    pdf.js-seamonkey from Isaac Schemm.
  * SeaMonkey now uses a new api for formatting regional data like time and
    date. Default is to use the application locale of the current SeaMonkey
    build. If you use a language pack or a different OS formatting this is
    usually not desired. You can change the formatting from the application
    locale to the regional settings locale (OS) in the preferences dialog under
    "Appearance".

SeaMonkey 2.53.18.2 uses the same backend as Firefox and contains the relevant
Firefox 60.8 security fixes.

SeaMonkey 2.53.18.2 shares most parts of the mail and news code with
Thunderbird. Please read the Thunderbird 60.8.0 release notes for specific
security fixes in this release.

Additional important security fixes up to Current Firefox 115.9 and Thunderbird
115.9 ESR plus many enhancements have been backported. We will continue to
enhance SeaMonkey security in subsequent 2.53.x beta and release versions as
fast as we are able to.

SeaMonkey-specific changes

  * SeaMonkey now uses gtk3 on Linux. If you experience a problem because of
    this please file a bug. Please try another OS theme first. Some of them are
    buggy and cause problems with SeaMonkey, Thunderbird and Firefox.
