linux/clock_settime: remove unnecessary vDSO definitions

Browse Source 
These definitions were added back before __ASSUME_POSIX_CPU_TIMERS
was removed.  There used to be a vsyscall to clock_getres() in
maybe_syscall_settime_cpu(), but that function was removed in commit
26889eac.  The presence of the vsyscall definitions means that platforms
that don't provide clock_getres as a vsyscall hit a symbol redefinition
warning in this file, becoming fatal with -Werror.  Removing the
vsyscall definitions is the obvious fix.

No change to generated code on x86_64.

* sysdeps/unix/sysv/linux/tile/sysdep.h
(HAVE_CLOCK_GETTIME_VSYSCALL): Move definition out of
assembly-specific section to avoid a redefinition warning.
