base-files: board_detect: Address shellcheck warnings

* SC2166 (warning): Prefer [ p ] && [ q ] as [ p -a q ] is not well
   defined.
 * SC2086 (info): Double quote to prevent globbing and word splitting.
 * SC2091 (warning): Remove surrounding $() to avoid executing output
   (or use eval if intentional).
