tests: inittest supports SKIP_WITH_LOW_SPACE

Test can set individually a higher value for required free space on
storage.

Note: it is not fully reliable since when 'brd' (ramdisk) device is used
this free space value is rather meanigul, but it might help
in case where a real filesystem is doing back-end for test devices.
