actions: run: allow to start scripts with arguments

Scripts passed to "Run" action are strings containing full path to script
with arguments. Debos fails to run it tr to start the whole string as a script.

Add possibility to start scripts with additional arguments.
Correct mount points for scripts with arguments in chrooted environment.
