[yocto] [PATCH 06/12] upgradehelper.py: only check email settings when -e is specified

[Robert Yang]

Fixed:
$ upgradehelper.py less
ERROR: smtp host not set! Sending emails disabled!
ERROR: 'From' address not set! Sending emails disabled!

Only check email settings when "-e" is specified can fix the problem.
