Andrey Semashev 1aaf946b18 Updated check for apt-add-repository capabilities. ...

In Ubuntu 20.04 there appeared an updated version of the
software-properties-common package in focal-updates, which ships a newer

capabilities, we have to parse its --help output instead.

Also, made source list processing more protected against spaces.
