btrfs/321: make the filter to handle older btrfs-progs
[FALSE ALERT]
With much older distros like SLE12SP5, which is using btrfs-progs 4.5.3,
test case btrfs/321 fails like this:
btrfs/321 QA output created by 321

But notice the header for each leaf, there is no flags for the leaf.
On newer btrfs-progs, the leaf header lines looks like this:
leaf 5423104 items 1 free space 2918 generation 7 owner CSUM_TREE
leaf 5423104 flags 0x1(WRITTEN) backref revision 1
It's two lines, not the old one line output.
The new behavior is introduced in btrfs-progs commit 9cc9c9ab3220
("btrfs-progs: print the eb flags for nodes as well"), included by v5.10
release.
So the test case doesn't handle older output format and failed to locate
the target leaf.
[FIX]
Instead of relying on the leaf flags line, use the much older
"leaf <bytenr> items" line as the filter target, so we can support much
older distros.
