make deb: Add devscripts dependency for make deb. Cleanup packages/bddeb.

Add a simple dependency check to "make deb" target for devscripts. Rework
a bit of the logic in package/bddeb to drop superfluous STD_NAMED_PACKAGES
to avoid duplication of requirements already listed in
(test-)?requiremets.txt. All "standard" packages can be assumed to have
either python3- or python- prefix if not listed in NONSTD_NAMED_PACKAGES.
This branch also moves logic inside write_debian_folder which is unneeded
up in main.
