modules/programs/bash: Fix ShellCheck warnings

https://github.com/koalaman/shellcheck/wiki/SC2086
Double quote to prevent globbing and word splitting.

Prefer `[ p ] && [ q ]` as `[ p -a q ]` is not well defined.

https://github.com/koalaman/shellcheck/wiki/SC2219
Instead of `let expr`, prefer `(( expr ))` .
