cronolog: Update download URL

The cronolog.org website seems to be dead. The project seems to have
moved to https://github.com/fordmason/cronolog but it is rather
unmaintained there also.

Use commit 8ea64c08afe54878ef3ce8489f9b1f6592515e59 ("added version 1.6.2
from 2001-05-04") for version 1.6.2.

Version 1.6.3 from 83f9e99d6bd5cb8f5cc06723f4d79d1265582340 ("added version
1.6.3 from 2004-02-07") does not seem to be functional:

    scratch/local/bee-buczek/cronolog/cronolog-1.6.3-0/source/configure --prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --libexecdir=/usr/libexec --sysconfdir=/etc --sharedstatedir=/var --localstatedir=/var --libdir=/usr/lib --includedir=/usr/include --datadir=/usr/share --infodir=/usr/share/info --mandir=/usr/share/man --exec-prefix=/usr
    configure: error: cannot find sources (bootstrap) in /scratch/local/bee-buczek/cronolog/cronolog-1.6.3-0/source or ..
