sm8350-common: Blob out audio HAL extensions

These targets are using prebuilt audio HAL and for some reason,
using the source-built liba2dpoffload breaks A2DP. Just use
prebuilt HAL extensions to avoid mismatches.
Build libtinycompress explicitly as that was built implicitly as
dependency of the audio HAL extensions previously.
