networkd: fix size of networkd binary

This patch fixes the size of networkd
Bug #775

before:

size systemd-networkd
   text	   data	    bss	    dec	    hex	filename
1493755	8424392	   2337	9920484	 975fe4	systemd-networkd

After

$ size systemd-networkd
   text	   data	    bss	    dec	    hex	filename
1493555	  35752	   2337	1531644	 175efc	systemd-networkd
