David Crawshaw 54b4a066d7 gl: add a comment for linux installation ...

OpenGL ES is not installed by default on linux distributions, which
can lead to a cryptic error. Add a comment after the #include
mentioning what packages contain OpenGL ES on Ubuntu, which is
helpfully printed in the error message. For example:

	$ go build golang.org/x/mobile/example/basic
	# golang.org/x/mobile/gl
	In file included from ../../mobile/gl/work.go:21:0:
	work.h:6:117: fatal error: GLES2/gl2.h: No such file or directory
	 #include <GLES2/gl2.h> // install on Ubuntu with: sudo apt-get install libegl1-mesa-dev libgles2-mesa-dev libx11-dev
