[PATCH v3] btrfs-progs: Add uninstall targets to Makefiles.

[Nils Steinger <nst@voidptr.de>]

v2: As Satoru Takeuchi pointed out, I forgot to remove $(libs) in the main
Makefile.

v3: David Sterba suggested not to remove the $(bindir) and $(libdir), since
those might be needed by other programs, even if the btrfs uninstallation
leaves them empty.
