install: Make wanpipe optional, use mirror if needed.

Currently, the ftp.sangoma.com server is not being
responsive, so this makes two improvements:

* Only install wanpipe if directed to, since most
  installations don't need this anyways
* If ftp.sangoma.com is unresponsive, don't keep
  retrying, since with 20 retries of 4 minutes each,
  this will retry up to 80 minutes, for no reason.
  Instead, fall back to using the Wayback Machine's
  copy of the tarball if needed.
