ae48a22a3d test: fixing failing system_tests/run_command under some Locales (Jadi)
Pull request description:
the run_command test under system_tests fails if the locale is anything
other than English ones because results such as "No such file or directory"
will be different under Non-English locales.
On the old version, a `ls nonexistingfile` was used to generate the error
output which is not ideal. In the current version we are using a Python one-liner
to generate a non 0 zero return value and "err" on stderr and check the
expected value against this.
