Remove patches for openh264 support
Context
We currently (or will when !1638 (merged) lands) patch noopenh264 to update API to that of openh264 2.0.0 and also gst-plugins-bad to fix a bad build version check. We have an open MR for the noopenh264 patch, and there is already a patch in master for our gst-plugins-bad issue.
Description
Once upstream MRs are merged and new releases are around, remove patches from noopenh264 and gst-plugins-bad.
Acceptance Criteria
No patches on noopenh264, don't patch the openh264 build for gst-plugins-bad.
