[PATCH v2 01/12] btrfs-progs: fix running lowmem check tests

[Josef Bacik <josef@toxicpanda.com>]

When I added the invalid super image I saw that the lowmem tests were
passing, despite not having the detection code yet.  Turns out this is
because we weren't using a run command helper which does the proper
expansion and adds the --mode=lowmem option.  Fix this to use the proper
handler, and now the lowmem test fails properly without my patch to add
this support to the lowmem mode.
