LU-930 doc: update URLs in man pages

Update the bug reporting URL to point at http://bugs.whamcloud.com/,
since current releases are not longer being made by Sun, and they
should not be getting bug reports about any 2.x releases.  Since all
of the man pages reference lustre(7), and the URL is also in the RPM
packages, we don't need to put the URL into every man page.
