build: Fix the GLES headers check 

GLES/glext.h and GLES2/gl2ext.h need to include GLES/gl.h and
GLES2/gl2.h respectively to get the GL types.

This used to work as autoconf used to only do a preprocessor pass in
AC_CHECK_HEADER(S), but now it also tries to compile a small test
program and thus the test failed.
