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.
