Temporarily unavailable for hacking on guix

[Maxime Devos]

Hi guix,

TL;DR: I won't be available for a while, so please remove me from guix-security and http://guix.gnu.org/en/security/ and don't expect replies on existing issues.

The computer I usually use (where the usual gpg, e-mail, git, IRC, guix itself ... is all set-up)  (no worries, there are back-ups) is somewhat broken (hardware, not software).

It should be relatively easy to fix, but I'll probably be taking my sweet time to actually fix it.

Greetings,

Maxime.
