Move some application specific stuff out of libutil

This commit does the following:
 - canonicalize_name is moved to libfstree
 - source_date_epoch is only used inside libfstree, so it's also moved
   over and can later be completely internalized
 - print_version is moved over to sqfshelper. Mainly so it doesn't end
   up in libsquashfs.so for no sane reason.
