ofono: Add python-pygobject to ofono-tests package DEPENDS
Some of the ofono-tests python scripts, such as test-modem and
receive-sms (22 in total) import gobject. Make the ofono-tests package
depend on python-pygobject.
Tested on the meta-intel fri2 BSP in a core-image-sato image. Assorted
ofono tests run correctly.
