On revision r225340 <https://trac.webkit.org/r225340> ANGLE was updated, but this update didn't took into account the previous changes that r216497 <https://trac.webkit.org/r216497> did over the eglplatform.h file.
Without this change, the WPE port is building the ANGLE target using the X11 types, which seems quite wrong.
Also this causes the build to fail on systems not having libx11 (like embedded ones).
