[distcc] Default job limits in distcc.1

Hi all,

It took me quite some time to figure out why "make CC=distcc -j5" with
DISTCC_HOSTS set to "localhost arrakis" would run 2 jobs on the local
machine and 3 jobs on the remote machine named "arrakis", when I would
have expected it the other way around.

Experiments revealed that the default job limit for localhost is 2, while
the limit for other hosts is 4. Reading the source code confirmed that.
The manual page doesn't mention the fact that localhost is handled
differently in that respect.

I think it would be great to mention this in distcc.1, so that newcomers
understand what happens. Below is a trivial patch doing just that
(hopefully my webmail client will not trash it).
