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 ef59542668d94b5ed077e16bc0eb18b057d3d1b4)
