add default Nix expression and patch for sysklogd. The patch allows sysklogd to
be compiled against kernel headers for the Linux 2.6 kernel. As it turns out many, if not all, distributions use 2.4 kernel headers for glibc. From my Fedora Core 3 system: $ rpm -qf /usr/include/linux/time.h glibc-kernheaders-2.4-9.1.87 The thing is that compilation now barfs, because some constants are needed that are defined in <linux/autoconf.h> which is empty the way we generate the kernel headers currently in nixpkgs. The source tree needs to be configured. Another challenge to solve :) svn path=/nixpkgs/trunk/; revision=3784
