Make second argument of gettimeofday as 'void *'
Also make the public prototype of gettimeofday declare its second argument with type "void *" unconditionally, consistent with POSIX. It is also consistent with POSIX. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.
