ifcfg-rh: accept TEAM connections also without DEVICETYPE setting

Allow omitting DEVICETYPE=Team or DEVICETYPE=TeamPort and accept
team connections based on the presence of TEAM_CONFIG/TEAM_MASTER
alone.

Also, check first for a team slave before checking for bond
slave. That is what initscripts do and matters if somebody wrongly
sets MASTER and TEAM_MASTER.
