Lintian complains that we use architecture all (see https://github.com/adobe/brackets-shell/blob/8bf61eea5fd33a52c1bc77b6e704589d17742c51/installer/linux/debian/DEBIAN/control) while also including a binary file.
Since we are providing separate 32 and 64 bit downloads, we should rewrite our control files with architecture i386 and amd64 separately.
