The time-related VDSO functionality was introduced in 2021 in
commit 87f3248cdb9a ("csky: Reconstruct VDSO framework") and
commit 0d3b051adbb7 ("csky: Add VDSO with GENERIC_GETTIMEOFDAY, GENERIC_TIME_VSYSCALL, HAVE_GENERIC_VDSO").
However the corresponding aux-vector entry AT_SYSINFO_EHDR was never
wired up, making these functions impossible to test or use.
The VDSO itself is kept as it also provides rt_sigreturn which is
exposed differently to userspace.
