linux: Use GLRO(dl_vdso_gettimeofday) on gettimeofday

The BZ#24967 fix (1bdda52fe92fd01b424c) missed the gettimeofday for
architectures that define USE_IFUNC_GETTIMEOFDAY.  Although it is not
an issue, since there is no pointer mangling, there is also no need
to call dl_vdso_vsym since the vDSO setup was already done by the
loader.

Checked on x86_64-linux-gnu and i686-linux-gnu.
