psmisc: bump to version 23.1

psmisc: bump to version 23.1

Forward port 0001-link-against-libintl.patch. Since now autoreconf works, move
the patch from Makefile.in to Makefile.am. Also, convert to git format.

Remove 0002-no-__progname.patch. Buildroot default uClibc and musl now provide
__progname.

Add a patch that adds the git-version-gen script to fix autoreconf.

Remove upstream patch.

Upstream switched to .xz tarballs.

Add upstream provided hashes.
