sm: Ask for the password for password based decryption (pwri)
* sm/decrypt.c (pwri_decrypt): Add arg ctrl. Ask for passphrase. * sm/export.c (export_p12): Mark string as translatable. * sm/import.c (parse_p12): Ditto.
This is finishes the support for PWRI.
The N_() marks are added so that we don't rely of the side-effect of
having the same strings in protect-tool.c
