install_prereq: Fix dependency install on aarch64.

Fixes dependency solutions in install_prereq for Debian aarch64
platforms. install_prereq was attempting to forcibly install 32-bit
armhf packages due to the aptitude search for dependencies.

Resolves: #37
(cherry picked from commit 2f02095da8fd35eedfa5e9713863924238c65baa)
