It's possible to run the tests with or without valgrind.  When testing
without valgrind, you're testing that basic functionality (eg. the
parsing of btrfs command output) works.  With valgrind you're
obviously testing that + that there are no memory errors.

The tests run very quickly indeed -- subsecond -- because they don't
run the appliance.

Currently configure sets VG to some impossible value
(VG_IS_NOT_INSTALLED IIRC) so any use of 'make check-valgrind'
anywhere will fail with an obvious error messasge.

That's possible too.  This isn't an external interface so we can
change it around in future.
