scripts: rename yocto-compat-layer to remove "compatible" nomenclature

scripts: rename yocto-compat-layer to remove "compatible" nomenclature

"Yocto Project Compatible" [1] is a programme which requires you meet
specific criteria including going through an application process - it is
not sufficient simply to run the script we have created here and have it
produce no warnings/errors. To avoid people being confused by the fact
that this script uses the term "compatible" or variations thereof,
substitute usage of that word with "check" instead. The functionality of
the script is unchanged.
