Fix matching of Proc::check_args if cmdline contains non-exe path

[JanLuca]

In the current version Proc::check_args matches all arguments of the cmdline to the needle to check if a program is already running. This check returns wrong result if for example the path /home/root/.local/share/remarkable/xochitl is somewhere in the cmdline arguments.

The new version just matches the first argument of the cmdline and only checks for further args if the first program is a known interpreter (sh, bash, python).

Fixes #127.
