Remove all of the remaining libcrypt code.zack/remove-libcrypt

Completing the removal of libcrypt, delete all of its actual code.
This patch contains only file removals:

git rm -r crypt
git rm include/crypt.h
git rm $(find sysdeps -name libcrypt.abilist)
git rm $(find sysdeps -name fips-private.h)
git rm $(find sysdeps -name 'md5-*' -o -name 'sha256-*' -o -name 'sha512-*')

For this patch (not the earlier ones, I'd still be waiting) I ran the
complete testsuite and found no *new* failures.  26 tests are failing
on my machine due to probable environment issues, but they were all
failing on trunk before I started making changes, and none of them
appear to have anything to do with this patchset.
