refactor(wpcarro/gnupg): Improve UX for gnupg/{import,export}.sh r/3629
TL;DR:
- Ensure that export.sh -> import.sh -> export.sh can round-trip without
  intermediate tools.
- Remove default values for variables like ${1}, which only seem to complicate
  things.
- Add `trap cleanup EXIT` to scripts.
- Remove noisy full-paths from `zip` (note: a more intuitive, less configurable
  `zip`, `unzip` should exist).
