linux: Enable vDSO for static linking as default (BZ#19767)
This patch assumes static vDSO is supported as default, it is now supported
on all current architectures that support vDSO.  It allows removing both
ALWAYS_USE_VSYSCALL define, which an architecture requires to explicit define
and USE_VSYSCALL (which defines vDSO only for shared or if architecture defines
ALWAYS_USE_VSYSCALL).

Checked with a build against all affected ABIs.

	[BZ #19767]
	* sysdeps/unix/sysv/linux/aarch64/sysdep.h (ALWAYS_USE_VSYSCALL):
	Remove definition.
