package/efl: fix build with mesa

efl does not compile with mesa without OpenGL ES because it checks for
GL_ES_VERSION_2_0 and declares own GLintptr and GLsizeiptr types if such
version is not defined, but mesa declares them too for OpenGL version
1.5, so fix it by add check also for OpenGL 1.5 where these types are
defined.

+Subject: [PATCH] evas gl - make GLintptr etc. also ndefed for GL_VERSION_1_5
+ fix typedef
+
+It seems that GL_VERSION_1_5 define == these provided by gl already. At
+least reading the mesa headers I do, so this should fix T7502
