pass: Fix dependencies on Darwin

password-store on Darwin does not pass unit tests in sandboxed
builds:

- 'openssl base64' is used on Darwin to compute base64. Add openssl
  to the environment of pass.
- t0200-edit-tests.sh tests 'pass edit', which uses hdid on Darwin.
  However hdid is not available in the sandbox.
