NNTPC: Minor patch to set process name to something sensible

[sthaug@nethelp.no]

Hi, I found I would like 'ps' to show something useful for each client.
So I added a call to 'setproctitle' to make it look like this:

	nntpcached: unknown@haraldt.p52.hioslo.no (158.36.144.135)

I just did a quick and dirty version for FreeBSD - for a more complete
version look at TITLEset() from nnrpd.c in the inn-1.5.1 distribution.

I also changed a couple of openlog() calls to use "nntpcached" instead
of argv[0]. This is just a cosmetic issue, I think it makes the syslog
output easier to read.

I'm happy to report that ntpcached is now very nice and stable for me,
I haven't had a crash for several days. There are still problems with
multiuser handling (several users accessing the same articles/overview),
but I'm sure we'll get these fixed also.
