btrfs-progs: move internal.h to common/

Create directory for all sources that can be used by anything that's not
rellated to a relevant kernel part, all common functions, helpers,
utilities that do not fit any other specific category.

The traditional location would be probably lib/ with all things that are
statically linked to the main binaries, but we have libbtrfs and
libbtrfsutil so this would be confusing.
