Log message:
Remove mk/find-prefix.mk usage from the security category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

---------------------
Noteworthy changes in version 1.6.0 (2015-08-26) [C25/A14/R0]

 * Added gpgme_set_offline to do a key listinging w/o requiring CRL.

 * Added gpgme_set_status_cb to allow a user to see some status
   messages.

 * Added an export mode for secret keys.

 * More precise error codes are returned if GnuPG >= 2.1.8 is used.

-------------------------------------------------------------

 * On Unices the engine file names are not not anymore hardwired but
   located via the envvar PATH.  All options to set the name of the
   engines for the configure run are removed.

 * If GPGME finds the gpgconf binary it defaults to using gpg2 or
   whatever gpgconf tells as name for the OpenPGP engine.  If gpgconf
   is not found, GPGME looks for an engine named "gpg".

 * New feature to use the gpgme I/O subsystem to run arbitrary
   commands.

 * New flag to use encryption without the default compression step.

 * New function to access "gpg-conf --list-dirs"

 * New configure option --enable-fixed-path for use by Android.
