x86: move rdtsc_barrier() into the TSC vread method
The *fence instructions were moved to vsyscall_64.c by commit
cb9e35dce94a1b9c59d46224e8a94377d673e204. But this breaks the
vDSO, because vread methods are also called from there.
Besides, the synchronization might be unnecessary for other
time sources than TSC.
[ Impact: fix potential time warp in VDSO ]
