This fixes a bug occurred with 0b3e3c637e.
Dead processes still appeared in ${top} under FreeBSD and OpenBSD. This was
because I forgot to update the g_time variable which is used as time stamp in
the process list.

Linux-specific code in top.cc was moved to linux.cc.
Redundant code (e.g. the parts sorting by CPU usage, CPU time or memory
usage) was removed. Sorting etc. happens in top.cc, whilst
platform-dependent code in linux.cc, freebsd.cc or openbsd.cc just
builds up the process table.
In the Linux code, some functions had a return value which was never
evaluated. They return void now.
I tested it on FreeBSD and Linux; The OpenBSD port does not compile
anyway. I changed the OpenBSD parts, too, so that it will be less
effort to get conky working under OpenBSD.
