Fix: Use getBuildConfig instead of direct access to bitbakeSettings

A lot of places in the code were using the global config when they
should be using the buildConfiguration specific one, if available.

ESDK mode not affected because it takes a flat config.
pathToBitbakeFolder not affected because it is in the general section.
