SCM_SRS: Improve fallback implemention to avoid unspecified behavior.

* libguile/numbers.h (SCM_SRS): Rewrite preprocessor test to avoid
  left-shifting negative integers, and to test more comprehensively for
  the behavior we need.  Rewrite fallback implementation to avoid
  unspecified behavior.
