bt_uuid_t is defined as a byte array, so it can cause alignment errors
on some architectures, when the two 64 bit halves are treated as u64s.
This patch ensures proper alignment across all architectures.

Fixes:
src/adapter.c: In function ‘bt_uuid_hash’:
src/adapter.c:3617:8: error: cast increases required alignment of target type [-Werror=cast-align]
  val = (uint64_t *)&uuid_128.value.u128;
        ^
cc1: all warnings being treated as errors
