[patch] do not print version string by default

[Mansour Moufid]

Hello everyone,

You may have heard about the law enforcement agents who are accused of
stealing some Silk Road bitcoins.  They used GPG at some point and the
version string is used as "evidence" to identify them -- which is of
course ridiculous but it is what it is.

See: https://twitter.com/wiretapped/status/582663354533195777

Let's not print the version string by default.

Yours,
Mansour
