btrfs-progs: Fix progs_extra build dependencies

The Makefile does not have a dependency path that builds dependencies
for tools listed in progs_extra.

E.g. doing make btrfs-show-super in a clean build environment results in:
    gcc: error: cmds-inspect-dump-super.o: No such file or directory
    Makefile:389: recipe for target 'btrfs-show-super' failed
