Merge lp:~mvo/pkgme-devportal/lib-overrides-fixes into lp:pkgme-devportal

[Michael Vogt]

Make the lib overrides work by making configglue case-sensitive and fixing the default for libgl1-mesa-glx (mvo)

This branch fixes some issues in my previous lib-overrides work:
- its "libGL.so.1" not "libgl.so.1" (case matters)
- the configglue code by default is not case-sensitive so that needs to be tweaks
- the example config is fixed to actually work
- the test is improved to really test the config values instead of the default values

Amazing how much issues such a small branch can have :/

adjust the naming to make the config file more readable

[Jonathan Lange (jml)]

Looks good. Thanks.

Please remove the XXX comment about lucid before landing.
 a) we don't deploy to lucid any more, or support it either
 b) tarmac will catch it anyway

devportalbinary/configuration.py: remove configglue.pyschema fallbacks as they should be no longer needed (thanks to jml for this!)
