[OE-core] [PATCH 2/2] webkitgtk: fix to build without opengl

[Chen Qi]

Currently, webkitgtk cannot be built if 'opengl' is not in distro
feature. The error message is like below:

  OpenGLShims.h:23:10: fatal error: GL/gl.h: No such file or directory

The required distro feature for webkitgtk is only 'x11'.

>From its source codes, libepoxy is an alternative option to build webkitgtk.
So fix to use it. In this way, we can successfully build out
webkitgtk if 'opengl' is not in distro features.

+Subject: [PATCH] fix to build with libepoxy
+
+In source codes, there are places checking USE(LIBEPOXY), but
+in cmake files, there's nowhere to handle it.
+
+Fix to define USE_LIBEPOXY to 1 if ENABLE_LIBEPOXY is turned on.
