Message:

Additions: X11: VMSVGA: gracefully exit VBoxClient process if has been VBoxDRMClient started, bugref:9637.

This commit fixes regression introduced in r141338. VBoxClient (--vmsvga) and VBoxDRMClient
processes cannot ran in parallel. Only one process is allowed to do VbglR3AcquireGuestCaps(VMMDEV_GUEST_SUPPORTS_GRAPHICS).
Therefore, once VBoxDRMClient takes over, VBoxClient should be terminated.
