To check for FITRIM tests used _require_fstrim() and
_test_batched_discard() but as _test_batched_discard() already
includes _test_fstrim() unify FSTRIM check throughout xfstests with
_require_batched_discard().

Stress btrfs' block group allocation and deallocation while running
fstrim in parallel. Part of the goal is also to get data block groups
deallocated so that new metadata block groups, using the same physical
device space ranges, get allocated while fstrim is running. This caused
several issues ranging from invalid memory accesses, kernel crashes,
metadata or data corruption, free space cache inconsistencies, free
space leaks and memory leaks.
