dev-db/freetds: remove old unused versions and files.

The versions between 0.91 and 1.00.41 were all unstable on every arch,
so I removed them in favor of v1.00.41. The old v0.91 is only still
required because it's stable on hppa (where v1.00.41 is not). The one
patch in the files directory was obsolete after the cleanup, so it too
has been removed.
