Subject: btrfs-progs: convert-tests: Add support for custom test scripts

Add support for custom convert test scripts, just like fsck tests.

Instead of generic convert tests, we need more specifically created images
for new convert tests.

This patch provide the needed infrastructure for later convert test
cases.
