man-pages.7: Update nonbreaking space advice

* Advise usage of \~ escape instead of \SPACE; the former, a groff
  extension from circa 1990, has been supported by Heirloom Doctools
  troff since 2005 and by mandoc since 2019.  The advantage is that
  \~ is an _adjustable_ non-breaking space, so it will typeset
  non-jarringly both in .EX/.EE examples when filling is off, and in
  normal running text (which is filled).
