Several tests uses both _filter_test_dir and _filter_scratch
concatenated by pipe to filter $TEST_DIR and $SCRATCH_MNT. However,
this would fail if the shorter string is a substring of the other
(like "/mnt" and "/mnt2").
This patch introduces new common filter function to safely call both
_filter_test_dir and _filter_scratch, and update tests and functions
to use this new function.
I checked this with btrfs/029, generic/409,410,411, and
generic/381,383, xfs/106,108 (which calls _filter_quota). Thanks
Eryu for advice.

Some tests require the scratch volume to be a block device,
although they don't do anything block device specific like
the device mapper tests. They actually only require a local
device and fail with network or overlay pseudo mount devices.
The same tests also try to mount the scratch device manually
after running _scratch_mkfs. For UBIFS, _scratch_mkfs simply
truncates the UBI volume and relies on the kernel to re-format
the volume on the next mount. This fails if the fs type is not
specified explicitly when mounting.
This patch replaces the block device requirement with a
generic check for a local device and adds a filesystem
specification to all manual mounts of the scratch device
to a mount point.

After some shared subtrees test (bind/slave/shared/private), maybe
some dentries isn't freed. For example, EBUSY maybe returned due to
some bugs. This patch tries to verify that.

This case will do function test for mount bind operation, it will
verify below semantics:
---------------------------------------------------------------------------
| BIND MOUNT OPERATION |
|**************************************************************************
|source(A)->| shared | private | slave | unbindable |
| dest(B) | | | | |
| | | | | | |
| v | | | | |
|**************************************************************************
| shared | shared | shared | shared & slave | invalid |
| | | | | |
|non-shared| shared | private | slave | invalid |
***************************************************************************
This case usees fsstress to produce a small random load, to make
sure basic operations on the bind mountpoints won't cause hang or
panic etc.
