With the addition of the `-p` populate option, SOURCE_DATE_EPOCH and
DETERMINISTIC_SEED support, it is possible to create fully reproducible
pre-populated filesystems. We should test them here.
v1 -> v2:
- Changed test group from parent to mkfs
- Fixed PROTO_DIR to point to a new dir
- Populate PROTO_DIR with relevant file types
- Move from md5sum to sha256sum
v2 -> v3
- Properly check if mkfs.xfs supports SOURCE_DATE_EPOCH and
DETERMINISTIC_SEED
- use fsstress program to generate the PROTO_DIR content
- simplify test output
v3 -> v4
- Add _cleanup function
v4 -> v5
- copy _cleanup from common/preamble
v5 -> v6
- remove debug typo/leftover

I think it's not good to be commit log, better to move this part ->

To match the _kill_fsstress, when I merge this patch I'll change this part to:
FSSTRESS_ARGS=`_scale_fsstress_args -d $PROTO_DIR -s 1 -n 2000 -p 2 -z
-f creat=15 \
-f mkdir=8 \
-f write=15 \
-f truncate=5 \
-f symlink=8 \
-f link=8 \
-f setfattr=12 \
-f chown=3 \
-f rename=5 \
-f unlink=2 \
-f rmdir=1`
_run_fsstress $FSSTRESS_ARGS
