Documentation: add lint-fsck-msgids
During the initial development of the fsck-msgids.txt feature, it has become apparent that it is very much error prone to make sure the description in the documentation file are sorted and correctly match what is in the fsck.h header file. Add a quick-and-dirty Perl script and doc-lint target to sanity check that the fsck-msgids.txt is consistent with the error type list in the fsck.h header file.
