Eric Sandeen ef85e7e285 btrfs-progs: Add default rules to Makefile
Add a default rule for any btrfs-$FOO or btrfs-$FOO.static
target, allowing it to be built from btrfs-$FOO.c along with
all the normal userspace objects.

This gets rid of a lot of the cut and pasted rules for
each individual command, and as an added bonus makes it
easy to build any btrfs-$FOO statically as well, i.e.

  # make btrfs-convert.static
