privoxy/tor:
 * revert r11684 - both features depending on wget even being compiled-in could be disabled at run-time => it's up to the user to ensure that external'ed wget is available, i.e. to add privoxy/tor to the list of external'ed services - either in freetz' menuconfig or in freetz' web-interface
 * refs #2364
