scripts: Simplify code with sys.exit(<string>)

Browse source 
Promote a handy and often-overlooked sys.exit() feature: Passing it a
string (or any other non-int object) prints it to stderr and exits with
status 1.

See the documentation at
https://docs.python.org/3/library/sys.html#sys.exit.

This indirectly prints some errors to stderr that previously went to
stdout.
