xfstests: renumber existing btrfs tests to start with 1
Current numbering is inheried from the single testsuite series. There are only 6 btrfs-specific tests and it makes more sense to start adding new ones at a more natural place than 300-something. There's no overlap with the old and new numbers and I hope there' will be no confusion when referencing them.

# Run fsstress to create a reasonably strange file system, make a
|
||||
# snapshot and run more fsstress. Then select some files from that fs,
|
||||
# run filefrag to get the extent mapping and follow the backrefs.
|
||||
# We check to end up back at the original file with the correct offset.
