xarray: port tests to kunit

Browse Source 
Minimally rewrite the XArray unit tests to use kunit.  This integrates
nicely with existing kunit tools which produce nicer human-readable output
compared to the existing machinery.

Running the xarray tests before this change requires an obscure
invocation

```
tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 \
  --kconfig_add CONFIG_TEST_XARRAY=y --raw_output=all nothing
```

which on failure produces

```
BUG at check_reserve:513
...
XArray: 6782340 of 6782364 tests passed
```

and exits 0.

Running the xarray tests after this change requires a simpler invocation

```
tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 \
  xarray
```

which on failure produces (colors omitted)

```
[09:50:53] ====================== check_reserve  ======================
[09:50:53] [FAILED] param-0
[09:50:53]     # check_reserve: EXPECTATION FAILED at lib/test_xarray.c:536

[09:50:53] # Totals: pass:28 fail:3 skip:0 total:31
[09:50:53] ===================== [FAILED] xarray ======================
```

and exits 1.

Use of richer kunit assertions is intentionally omitted to reduce the
scope of the change.

Enable this option to test the Xarray code at boot.
KUnit tests run during boot and output the results to the debug log
in TAP format (http://testanything.org/). Only useful for kernel devs
running the KUnit test harness, and not intended for inclusion into a
production build.
For more information on KUnit and unit tests in general please refer
to the KUnit documentation in Documentation/dev-tools/kunit/.
If unsure, say N.
