Introduce _post_mount_hook(), which will be executed after mounting
scratch/test.
It's quite useful for fs(OK, only btrfs yet, again) which needs to
use ioctl other than mount option to enable some of its feature.
Now only btrfs quota needs this hook to allow enabling quota to be
enabled for *ALL* existing test cases.
This should dramatically improve the test coverage to expose quota
related bugs.
