Jon Roelofs 14da7e5194 [llvm][Support] Avoid silent truncation of socket paths (#190869) ...

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.
