selftests: vDSO: vdso_test_correctness: Use facilities from parse_vdso.c
The soname from the vDSO is not a public API. Furthermore it requires
libc to implement dlsym() and friends.
Use the facilities from parse_vdso.c instead which uses the official
vDSO ABI to find it, aligned with the other vDSO selftests.

selftests: vDSO: vdso_test_correctness: Handle different tv_usec types
On SPARC the field tv_usec of 'struct timespec' is not a 'long int', but
only a regular int. In this case the format string is incorrect and will
trigger compiler warnings.
Avoid the warnings by casting to 'long long', similar to how it is done for
the tv_sec and what the other similar selftests are doing.

correct.

The test uses the kselftest.h framework and declares in its testplan to

the testplan would not be satisfied anymore and the test would fail.
Apparently that never happened, so the clockids are always available.

Currently this results in the following output:

# AT_SYSINFO_EHDR is not present!
This output is incorrect, as "1..16" still requires the subtest lines to
be printed, which isn't done however.
Switch to the correct skipping functions, so the output now correctly
indicates that no subtests are being run:
