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.
