Fix grgsm_livemon Qt crash in headless Docker container

Browse Source 
Set QT_QPA_PLATFORM=offscreen for both grgsm_livemon and
grgsm_scanner to prevent SIGABRT when no X11 display is available.
grgsm_livemon uses GNU Radio which loads Qt plugins — without a
display, Qt aborts with "could not connect to display".
