generic: test for fsync of file with xattrs
Test that xattrs are not lost after calling fsync multiple times
with a filesystem commit in between the fsync calls.
This test is motivated by a bug found in btrfs which is fixed by a
patch for the linux kernel titled:
Btrfs: fix xattr loss after power failure
