trans/mtab: ignore translators that do not implement file_get_source
Previously, the mtab translator would guess the source of a filesystem
translator from its last argument. This made all kinds of
non-filesystem translators appear in /proc/mounts, causing severe
problems due to umount --all removing vital passive translator
records.
Fix this by ignoring all translators that do not explicitly implement
file_get_source.
* trans/mtab.c (mtab_populate): Ignore translators that do not
implement file_get_source.
