[autotest] Update some afe_utils methods to use host._afe_host.

Updated the following methods to use local host._afe_host.labels:
- get_labels
- get_board
- get_os
- get_build

Also updated callers as well since it used to return a list of Label
objects, now it returns a list of strings.

BUG=None
TEST=unittests and tryjob on wolf-paladin with hwtests.
