btrfs: add test for btrfs-progs restore feature
This is a regression test to verify that the restore feature of btrfs-progs
is able to correctly recover files that have compressed extents, specially when
the respective file extent items have a non-zero data offset field.
This issue is fixed by the following btrfs-progs patch:
