[PATCH V3] xfstests: fix common filter include in filter.btrfs

[Eric Sandeen <sandeen@xxxxxxxxxxx>]

Not sure how this happened, but filter.btrfs including
itself leads to immense sadness for any file that includes it.
(I got a segfault when I tried to run 307)

It should be including ./common/filter not ./common/filter.btrfs

cripes, I'm sorry that took 3 times to get right :/
