The BLKID and ELFUTILS strings were present twice. Let's reaarange things so that each times requires definition in exactly one place. Also let's sort things a bit: the "heavy hitters" like PAM/MAC first, then crypto libs, then other libs, alphabetically, compressors, and external compat integrations. I think it's useful for users to group similar concepts together to some extent. For example, when checking what compression is available, it helps a lot to have them listed together. FDISK is renamed to LIBFDISK to make it clear that this is about he library and the executable.
