[0/7] fstests: add tests for btrfs' raid-stripe-tree feature

Message

Add tests for btrfs' raid-stripe-tree feature. All of these test work by
writing a specific pattern to a newly created filesystem and afterwards
using `btrfs inspect-internal -t raid-stripe $SCRATCH_DEV_POOL` to verify
the placement and the layout of the metadata.

The md5sum of each file will be compared as welli after a re-mount of the
filesystem.
