common/rc: teach _scratch_mkfs_sized to set a size on an xfs realtime volume

Generally speaking, tests that call _scratch_mkfs_sized are trying to
constrain a test's run time by formatting a filesystem that's smaller

If fstests has been configured to create files on the realtime device by

volume size will instead be running with a huge realtime device.  This

generic/574: fix sporadic failure with test_dummy_encryption

When the "test_dummy_encryption" mount option is specified, the
fs-verity file corruption test generic/574 is flaky; it fails about 1%
of the time.  This happens because in the three test cases where a
single byte of the test file is corrupted, sometimes the new byte
happens to be the same as the original.  This is specific to
test_dummy_encryption because the encrypted data is nondeterministic
(and appears random), unlike the unencrypted data.

Fix this by corrupting 5 bytes instead of 1, so that the probability of
failure becomes effectively zero.

overlay: add unionmount tests with nested overlay

These tests use an overlay mount as lower layer for a nested overlay.
That provides test coverage for a lower layer with null uuid and
lower layer with real inode numbers that use the high xino bits.

overlay: add unionmount tests with multi lower layers

The tests with multi lower layers rotate the upper layer into a lower
layer on specific operations such as mkdir, rename and link.
That provides test coverage for redirect_dir and index features.

The following variations are covered:
1. All layers all on scratch fs (--ov=10 --samefs)
2. All layers on scratch fs expect for lowermost on test fs (--ov=10)
3. Lowermost layer on test fs, one layer on tmpfs and the rest
   on sratch fs (--ov=10 --maxfs=1)
4. Lowermost layer on test fs, one layer on scratch fs and the rest
   are unique tmpfs instances (--ov=10 --maxfs=10)

overlay: run unionmount testsuite test cases

Add support for running unionmount-testsuite from xfstests.
This requires that unionmount-testsuite is installed under src dir or
that UNIONMOUNT_TESTSUITE variable points to the location of the
testsuite.  It also requires a recent version of unionmount-testsuite
that supports setting basedir path via UNIONMOUNT_* environment variables.

Add tests for three basic configurations:
1. overlay with upper/lower on same fs
2. overlay with upper/lower not on same fs without xino
3. overlay with upper/lower not on same fs with xino

The samefs test uses scratch partition for lower/upper layers.
The non samefs tests use the scratch partition for upper layer and the
test partition for lower layer.
