As part of the work enabling OpenH264 in
WebRTC it was discovered that some of its code triggers
an UBSan errors:
third_party/openh264/src/codec/common/inc/golomb_common.h:103:3: runtime error: shift exponent 32 is too large for 32-bit type 'uint32_t' (aka 'unsigned int')
third_party/ffmpeg/libavcodec/h264_cavlc.c:585:54: runtime error: index -1 out of bounds for type 'VLC [15]'
Suppress such errors since this source code is out of our control.
This CL also includes a new NetEq suppression.

By doing an unsigned instead of a signed addition, we get the exact
same machine code (in non-UBSan builds), but no longer trigger
undefined behavior since unsigned overflow is defined behavior.
