Subject: [PATCH] btrfs-progs: tests: support testname glob

To run a given test set the variable TEST like

 $ make test TEST=002-bad-transid
 $ make test TEST=002-*

and only tests matching the value will be run. The pattern is glob and
pased to 'find -name'.

The convert tests do not follow the fsck and misc layout and are skipped
if TEST is set.
