When the name is too long to fit in sockaddr_un::sun_path's 104 character buffer, we now surface the error condition, rather than silently truncating and failing the test with an "address in use Bind error". We also shorten the name a bit to give more headroom on CI systems that define an explicit TMP_DIR that acts as a prefix to the path created by these tests.
