package/privoxy: fix build with root

Fix the following build failure when the configuration files are
installed as root:

id: 'privoxy': no such user
******************************************************************
 WARNING! WARNING! installing config files as root!
 It is strongly recommended to run privoxy as a non-root user,
 and to install the config files as that user and/or group!
 Please read INSTALL, and create a privoxy user and group!
*******************************************************************
make[1]: *** [GNUmakefile:861: install] Error 1

This failure is probably raised since the addition of the package in
commit f8a263fe361ab37ec6765b9ff6478c3b15e3d139 and
https://www.privoxy.org/gitweb/?p=privoxy.git;a=commit;h=26baf6bcc0b5db47b8cf5c55eece0614712b5180
