In order to keep tests from hanging forever, this adds an alarm signal
to each test run. This assumes an individual test doesn't take longer
than 30 seconds.

The harness was still using old-style GNU named initializer syntax.
Fix this so Clang will stop warning:
seccomp_bpf.c:2924:1: warning: use of GNU old-style field designator extension
[-Wgnu-designator]
./../kselftest_harness.h:147:25: note: expanded from macro 'TEST'

./../kselftest_harness.h:172:5: note: expanded from macro '__TEST_IMPL'
fn: &test_name, termsig: _signal }; \

I've stumbled over the current macro-expand behaviour of the test
harness:
$ gcc -Wall -xc - <<'__EOF__'
TEST(macro) {
int status = 0;
ASSERT_TRUE(WIFSIGNALED(status));
}
TEST_HARNESS_MAIN
__EOF__
$ ./a.out
[==========] Running 1 tests from 1 test cases.
[ RUN ] global.macro
<stdin>:4:global.macro:Expected 0 (0) != (((signed char) (((status) & 0x7f) + 1) >> 1) > 0) (0)
global.macro: Test terminated by assertion
[ FAIL ] global.macro
[==========] 0 / 1 tests passed.
[ FAILED ]
With this change the output of the same test looks much more
comprehensible:
[==========] Running 1 tests from 1 test cases.
[ RUN ] global.macro
<stdin>:4:global.macro:Expected 0 (0) != WIFSIGNALED(status) (0)
global.macro: Test terminated by assertion
[ FAIL ] global.macro
[==========] 0 / 1 tests passed.
[ FAILED ]
The issue is very similar to the bug fixed in glibc assert(3)
three years ago:

Since seccomp_get_metadata() depends on CHECKPOINT_RESTORE, XFAIL the
test if the ptrace reports it as missing.

When a test process is not able to write to TH_LOG_STREAM, this step
mechanism enable to print the assert number which triggered the failure.
This can be enabled by setting _metadata->no_print to true at the
beginning of the test sequence.
Update the seccomp-bpf test to return 0 if a test succeeded.
This feature is needed for the Landlock tests.

Add ReST metadata to kselftest_harness.h to be able to include the

Remove the TEST_API() wrapper to expose the underlying macro arguments

The seccomp/test_harness.h file contains useful helpers to build tests.
Moving it to the selftest directory should benefit to other test
components.
Keep seccomp maintainers for this file.
