Since btrfs always return the whole extent even part of it is shared
with other files, so the hole/extent counts differs for "file1" in this
test case.
For example:
/------ File 1 Extent 0-------------\
/ \
|<----------Extent A------------------>|
\ / \ /
\ File 2/ \ File 2/
Ext 0~4K Ext 64k~68K
In that case, fiemap on File 1 will only return 1 large extent A with
SHARED flag.
While XFS will split it into 3 extents, first and last 4K with SHARED
flag while the rest without SHARED flag.
This makes the test case meaningless as btrfs doesn't follow such
assumption.
So black list btrfs for this test case to avoid false alert.
