x86: Fix x32 syscall build

[Adhemerval Zanella]

Working on the vDSO refactor I noted that x86_64/x32 build is broken
due some vdso declaration in syscall.list that is shadowing the
default x86 implementation.  This patch fixes it by removing the
auto syscall generation and make x32 uses the default Linux x86
code.

Tested on x32, ok to commit?

	* sysdeps/unix/sysv/linux/x86_64/x32/syscalls.list (gettimeofday):
	Remove definition.
	(time): Likewise.
