We need to ensure that all xorg modules are linked with
SECURITY_X_LDFLAGS to ensure that they will be able to resolve their run
time dependencies. The approach of listing each driver in
security_flags.inc lets less frequently used drivers be run-time
broken. Move the flag logic into xorg-driver-common.inc so that all
xorg modules from all layers will have the correct security flags used.
