selftests: vDSO: vdso_test_abi: Use UAPI system call numbers

SYS_clock_getres might have been redirected by libc to some other system
call than the actual clock_getres. For testing it is required to use
exactly this system call.

Use the system call number exported by the UAPI headers which is always
correct.
