The ENABLE_COMAPT_VDSO symbol is only used by arm64 and only for the time-related functionality. There should be no new users, so it doesn't need to be in the generic vDSO code.
Move the logic into arm64 architecture-specific code and replace the explicit define by the standard '#ifdef __aarch64__'.
