send_signal test returns static codes from the subtests which
nobody looks at, let's rely on the CHECK macros instead.

Export test__skip() to indicate skipped tests and use it in
test_send_signal_nmi().

Now that test__printf is a simple wraper around printf, let's drop it
(and test__vprintf as well).

This patch changes how test output is printed out. By default, if test
had no errors, the only output will be a single line with test number,
name, and verdict at the end, e.g.:
#31 xdp:OK
If test had any errors, all log output captured during test execution
will be output after test completes.
It's possible to force output of log with `-v` (`--verbose`) option, in
which case output won't be buffered and will be output immediately.
To support this, individual tests are required to use helper methods for
logging: `test__printf()` and `test__vprintf()`.

Some setups (e.g. virtual machines) might run with hardware perf events
disabled. If this is the case, skip the test_send_signal_nmi test.
Add a separate test involving a software perf event. This allows testing
the perf event path regardless of hardware perf event support.
