[bug #64824] Can't collect data with hostname is more 64 chara

[Albert Chu]

Follow-up Comment #1, bug #64824 (project freeipmi):

(sorry for late response, was on leave)

Googling around, I guess the issue has been that gethostname() (on almost all
systems) returns a max of 64 bytes (it's a linux kernel definition), so most
people use MAXHOSTNAMELEN as their "max hostname" buffer size (which I did
here).

But technically, that need not be the case, as when you input a hostname on
the command line, that's not related to gethostname() at all.

I agree on a fix, but it will take a little time to peel MAXHOSTNAMELEN away
and ensure things are portable (b/c MAXHOSTNAMELEN is defined in headers on
most systems).
