Fix build errors under FreeBSD

Makefile.am:  top.c was enlisted as Linux-only source, though it is
required for conky on every operating system.

conky.[ch]:  top_running definition was inside #ifdef __linux__, though
required by top.c on every operating system.

freebsd.c:  Change return type of update_*() to int, as required by
common.h; remove free_all_processes() as it is defined by top.c.  The
changes done to freebsd.c must be done to netbsd.c and openbsd.c, too.
I did not do it as I have no opportunity to test conky under NetBSD or
OpenBSD.
