broadband-modem: prefer specific access tech checks over generic +CGREG access tech (bgo #696705)

Browse Source 
If the modem has specific access technology checks, don't override them
with the generic access technology from +CGREG responses, since that
doesn't have the granularity that specific checks do.  For example, the
+CGREG response only indicates UMTS, and cannot indicate HSDPA, HSUPA,
HSPA, HSPA+, DC-HSPA, etc.
