Print firmware version in tab screen
In bug reports with screen shots of the firmware screens with tab
pressed, it would be extremely useful to see the version of the
currently running firmware and the read-only firmware, so output
this information.
BUG=none
TEST=press TAB at dev screen, see firmware versions printed on the
screen.
