[Support] Error if SocketPath is too long (#148903)
If the path is longer than sockaddr_un's buffer, it will be truncated,
at which point it may become indistinguishable from similar truncated
paths. This will cause `bind` to fail with an "Address already in use"
error. There is some existing code that checks `fs::exists` to catch
these errors, but since `fs::exists` compares the full un-truncated
paths, a too-long path will prevent those checks from working.
