vdso_test_abi contains a batch of tests that verify the validity of the
vDSO ABI.

When a vDSO symbol is not found the relevant test is skipped reporting
KSFT_SKIP. All the tests return values are then added in a single
variable which is checked to verify failures. This approach can have
side effects which result in reporting the wrong kselftest exit status.

Fix vdso_test_abi verifying the return code of each test separately.
