Replace the NULL checks with the more specific and idiomatic NULL macros.

Currently, these macros are only really documented near the bottom of
https://www.kernel.org/doc/html/latest/dev-tools/kunit/api/test.html#c.KUNIT_FAIL.
E.g. it's likely someone might just not realize that
KUNIT_EXPECT_STREQ() exists and instead use KUNIT_EXPECT_FALSE(strcmp())
or similar.
This can also serve as a basic smoketest that the KUnit assert machinery
still works for all the macros.

Add two new tests to the example test suite, both of which are always
skipped. This is used as an example for how to write tests which are
skipped, and to demonstrate the difference between kunit_skip() and
kunit_mark_skipped().
Note that these tests are enabled by default, so a default run of KUnit
will have two skipped tests.

As tests are added to kunit, it will become less feasible to execute
all built tests together. By supporting modular tests we provide
a simple way to do selective execution on a running system; specifying
CONFIG_KUNIT=y
CONFIG_KUNIT_EXAMPLE_TEST=m
...means we can simply "insmod example-test.ko" to run the tests.
To achieve this we need to do the following:
o export the required symbols in kunit
o string-stream tests utilize non-exported symbols so for now we skip
building them when CONFIG_KUNIT_TEST=m.
o drivers/base/power/qos-test.c contains a few unexported interface
references, namely freq_qos_read_value() and freq_constraints_init().
Both of these could be potentially defined as static inline functions
in include/linux/pm_qos.h, but for now we simply avoid supporting
module build for that test suite.
o support a new way of declaring test suites. Because a module cannot
do multiple late_initcall()s, we provide a kunit_test_suites() macro
to declare multiple suites within the same module at once.
o some test module names would have been too general ("test-test"
and "example-test" for kunit tests, "inode-test" for ext4 tests);
rename these as appropriate ("kunit-test", "kunit-example-test"
and "ext4-inode-test" respectively).
Also define kunit_test_suite() via kunit_test_suites()
as callers in other trees may need the old definition.
