[bt][common] static_cast for explicit truncation
In a test helper where we convert an integer wider than 1 byte to an
array of uint8_t, we truncate the lowest byte of the integer into the
current byte of the array. This truncation was implicit, triggering a
-Wno-conversion warning, so use a static_cast to make it explicit.
