Subject: [PATCH] weechat: extending expression with extraBuildInputs

make it easily possible to extend current buildInputs using override function.
eg.:

  weechat.override { extraBuildInputs = [ pythonPackages.pync ]; }

i've removed pync since its plugin dependency which can now be added via
extraBuildInputs.
