Back-merge r22229:22234 from /nmap-releases/5.51.

  r22234 | david | 2011-02-11 14:33:33 -0800 (Fri, 11 Feb 2011) | 4 lines
  
  Add an openssl guard around the require of tns in oracle-brute and
  oracle-enum-users. The tns library makes a call to
  openssl.rand_pseudo_bytes at its top level.

  r22232 | david | 2011-02-11 14:28:18 -0800 (Fri, 11 Feb 2011) | 4 lines
  
  Put an openssl guard around the importing of ssh2 in
  ssh2-enum-algos.nse. Otherwise it fail in --script-updatedb when
  configured --without-openssl.

  Allow whitespace at the end of the go_to_host pattern. On Windows,
  there's a '\r' at the end of the string, so the pattern didn't match.
