x264: fix build error because of incorrect macro definition.

Fix x264 package as we did in 21.09, the original macro definition
is incorrect and lead to build fail.

The root cause is we cannot provide gpac* devel package in our
build env, so we need to set correct macro to disable it.

On the other hand, X264 is set to disable/exclude status on
OpenEuler 2109 official OBS build server.
