Bugzilla Bug 241212

The 'adzapper' program (and probably other 'squid' redirectors) depends on
net-proxy/squid.
Squid isn't necessary to use it, it can be used for example with
net-proxy/polipo (which I use right now).

attached ebuild contains a simple fix to add a 'squid' use flag.

Reproducible: Always

Steps to Reproduce:
1.emerge -p adzapper

Actual Results:  
These are the packages that would be merged, in order:

Expected Results:
