Description: Hardcode using bash as make's shell
 On Debian/Ubuntu the default shell is dash, and builds are done with SHELL
 overridden to dash. Since archlinux-keyring now has Bash-isms in the
 install and uninstall targets (for {} expansion), and rewriting it to drop
 this is inconvenient (because we'll have to repeat the path prefixes),
 hardcode the use of Bash instead. Use /bin/bash to be compatible with distros
 that have not finished /bin -> /usr/bin migration yet.
