Subject: cmake: Require Mako >= 0.7

Piglit began requiring Mako 0.7 as of commit ac1f382 "dispatch:
Generate piglit-dispatch from Khronos XML".

Piglit has required Mako for a long time, and CMake did check for Mako.
But CMake didn't check the version. This patch fixes CMake to require
Mako >= 0.7 and to provide the below hint on failure:

  Hint: Try installing Mako with `pip install --user --upgrade Mako`
