don't truncate .go files, do an atomic rename to prevent SIGBUS

* module/system/base/compile.scm (call-with-output-file/atomic): New
  proc, outputs to a tempfile then does an atomic rename. Prevents SIGBUS
  if a compiled file is truncated and rewritten, as the file's objcode is
  mmap'd in.
  (compile-file): Use the new helper.
