My signatures for Linux i386/amd64 builds (made with a VirtualBox VM)

I have completed the Linux builds with a VM, this is the first step toward the other goal of [using docker containers instead](https://github.com/devrandom/gitian-builder/issues/53).

My public signature can be found at [keybase](https://keybase.io/gdm85/key.asc) or public keyservers through email address

**NOTE**: the extra newlines have been put there by current gitian-builder and I did not remove them after signing otherwise my signature wouldn't match.
