scripts: consolidate code to find bitbake path

Several of these scripts were using duplicated code (and slightly
different methods) to find the path to bitbake and add its lib
subdirectory to the Python import path. Add some common code to do this
and change the scripts to use it.

Fixes [YOCTO #5076].
