test: spl: Support testing LEGACY_LZMA filesystem images

Browse Source 
These will soon be supported, so we need to be able to test it. Export the
lzma data and generally use the same process in spl_test_mmc_fs as
do_spl_test_load.  If we end up needing this in third place in the future,
it would probably be good to refactor things out.
