[PATCHv3] libmbim-glib, proxy: add a configure flag to set the user ID of MBIM proxy

[Roshan Pius]

Hi Aleksander,

I'll port the same patch to libqmi & will send the patch in sometime.
How do we want to handle chown'ing the devices to the specific user? We'll
need to edit the udev rules to assign the devices to the specified user.
But, From what i can see the udev rules to detect the modems are currently
owned by modemmanager & this particular username flag is residing in
libmbim/libqmi.
