Fixes regarding first time use

See merge request t-5/PulseAudioParametricEq!2

Restarting now is done in one line, doesn't involve temp files and the
process is never closed.

Restarting failed when no executable calling pulseaudio_parameq.py
was present at /usr/bin. Now starts independently from where the
program was called and if such file is present or not.

Installing pulsectl for a different python executable when pip3
is using a different python executable, eg: pip3.10
