sysutils: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

sysutils: Remove SHA1 hashes for distfiles

Log message:
Updated sysutils/dmsdos to 0.9.2.3-pre2-alt2
----------------------------------------------------------------------
  The project is long time abandoned but it can be still usable to rescue
  data from old STACKER and DOUBLESPACE volumes.

  The version dmsdos-0.9.2.3-pre2-alt2 is based on patches found at
    http://packages.altlinux.org/en/Sisyphus/srpms/dmsdos/get

   2012-06-07 Fr. Br. George <george at altlinux.ru> 0.9.2.3-alt2
      - Fix gcc4.6 build

   2012-03-25 Fr. Br. George <george at altlinux.ru> 0.9.2.3-alt1
      - Initial build

  The modified version disables kernel code build which allows
  to build userspace tools for volume dump.

(pkgsrc changes)
 - LICENSE=       gnu-gpl-v2
 - Drop two patches, alt2 version included them.

Log message:
Add SHA512 digests for distfiles for sysutils category

Problems found with existing digests:
	Package memconf distfile memconf-2.16/memconf.gz
	b6f4b736cac388dddc5070670351cf7262aba048 [recorded]
	95748686a5ad8144232f4d4abc9bf052721a196f [calculated]

Problems found locating distfiles:
	Package dc-tools: missing distfile dc-tools/abs0-dc-burn-netbsd-1.5-0-gae55ec9
	Package ipw-firmware: missing distfile ipw2100-fw-1.2.tgz
	Package iwi-firmware: missing distfile ipw2200-fw-2.3.tgz
	Package nvnet: missing distfile nvnet-netbsd-src-20050620.tgz
	Package syslog-ng: missing distfile syslog-ng-3.7.2.tar.gz

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Import dmsdos-0.9.2.3pre2 -- this is the userland part of some code
which can access files on DBLSPACE compressed MSDOS volumes.
Not maintained, but it just helped me to salvage files from an old
harddisk, so I thought it is worth keeping.
(It can be integrated into the "mc" norton-commander clone - you'll
find out details in its documentation.)
