Fix unaligned memory access detected by UBSAN

Recently, Chromium added -fsanitize=alignment for `is_ubsan=true`,
and due to this, unaligned memory access was found in several places,
and chromium roll is currently blocked.
Modify unaligned memory access in rtc_base/byte_order.h to use memcpy.
Since libaom and libsrtp perform unaligned memory accesses, add them
to the suppression list.
Also, remove any mention of yasm from the UBSAN suppression list,
as yasm is no longer used.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
