clone needs to resolve the paths of the involved subvolumes in the target
fs from their UUIDs. When doing so it might need to strip the prefix
that is mounted as the root of the fs from those paths.
It didn't do so correctly when processing the source of "clone" commands

Current common.local doesn't handle lowmem mode well.
It passes "--mode=lowmem" alone with "--repair", making it unable to
check lowmem mode.
It's caused by the following bugs:
1) Wrong variable in test/common.local
We should check TEST_ARGS_CHECK, not TEST_CHECK, which is not defined
so we never return 1.
2) Wrong parameter passed to _cmd_spec() in test/common
This prevents us from grepping the correct parameters.
Fix it.

2) Compressed inline extent
Cause lowmem mode to find mismatch on inline len and item len.
