libcollectdclient: fix build

I unified the `meta` field from `collectd` here too.

pkgs/by-name/li/libcollectdclient/package.nix

···
 { lib, collectd }:
 
-collectd.overrideAttrs (oldAttrs: {
+collectd.overrideAttrs (prevAttrs: {
   pname = "libcollectdclient";
+
   buildInputs = [ ];
 
-  configureFlags = (oldAttrs.configureFlags or [ ]) ++ [
+  configureFlags = (prevAttrs.configureFlags or [ ]) ++ [
+    "--with-perl-bindings=no"
     "--disable-daemon"
     "--disable-all-plugins"
   ];
 
   postInstall = "rm -rf $out/{bin,etc,sbin,share}";
 
-  meta = with lib; {
+  meta = {
     description = "C Library for collectd, a daemon which collects system performance statistics periodically";
-    homepage = "http://collectd.org";
-    license = licenses.gpl2;
-    platforms = platforms.linux; # TODO: collectd may be linux but the C client may be more portable?
-    maintainers = [

     ];
   };
