Clang-tidy: Ignore variable name length and .c/.cc include warnings

After some internal discussion it was decided that we should ignore name
variable length tidy warnings. Otherwise we would have warnings for
every variable that is under three characters long.

Additionally we will also ignore any warnings when including non header
files as the Unity library in our build system uses this excessively
