omxh264enc: set profile/level using OMX_VIDEO_PARAM_AVCTYPE as well

Browse source 
The OMX specification defines two API to set the AVC profile and level:
using OMX_VIDEO_PARAM_PROFILELEVELTYPE and OMX_VIDEO_PARAM_AVCTYPE.

We were already supporting the former but not the latter. We are now
setting both so implementation don't have to rely on a specific one.
