avcodec/amfenc_hevc: set default gops_per_idr 1

Previously gops_per_idr default 60 would make amd gpu encoding hevc
has erratic seek bar behaviour as descripted in this ticket:
https://trac.ffmpeg.org/ticket/7272

This bad default is already fixed in newer AMF headers:
https://github.com/GPUOpen-LibrariesAndSDKs/AMF/blob/master/amf/public/include/components/VideoEncoderHEVC.h

Fixes ticket #7272.
