[OE-core] [PATCH] insane: add qa check for lowercase recipe name

[Yeoh Ee Peng]

Since we disabled uppercase characters in overrides a few releases ago,
uppercase characters in recipe names (and for that matter, distro and
machine names) cannot be supported due to their reliance upon overrides
including the name.

QA check will produce an warning message when it verify that recipe
name is not lowercase.
