            Log:
            test if ModemManager can create /sys/class/net/*/qmi/pass_through file

Recently, various modem users reported that SELinux prevents the
ModemManager service from working with netlink route sockets and
from creating the /sys/class/net/*/qmi/pass_through file. The TC
does not reproduce the situation.

In order to support the full functionality of ModemManager service,
I believe that SELinux policy should allow these actions. The TC
looks for appropriate policy rules.

The TC covers BZ#2145005, BZ#2149560 and BZ#2149954.
