cogl-1.0: : don't require eglmesaext.h

Starting with 1.22.8 cogl code unconditionally includes eglmesaext.h.
Change configure.ac so that eglmesaext.h is only included if it actually
exists.

+Subject: [PATCH] configure.ac: don't require eglmesaext.h
+
+E.g. the Vivante EGL implementation does not provide eglmesaext.h.
+
+The commit moves the check for header file existence outside of the
+check for existence of a egl packageconfig and makes the existence
+of eglmesaext.h optional.
+
+fixes commit fb1acfec ("Fix building against libglvnd-provided EGL headers")
