[PATCH] proxy.cgi: Suppress Squid version by default

["Peter Müller" <peter.mueller@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1251 bytes --]

While hiding version information does not come with any _actual_
security improvements, it is generally a good thing to do so by default:
Attackers will still be able to reasonably guess or enumerate the
software version running, but need to conduct additional effort to do
so, hence more likely raising alerts and drawing attention on their
operation.

In addition, we suppress version details somewhere else in IPFire 2.x by
default, too (e. g. Unbound and Apache), so we can justify this patch by
aiming to stay consistent, I guess. :-)
