The `bootstrap` build mode never calls `_export_gpg_publickey`, so even if the GPG key is passed with the `-g` option and thus the `gpg_key` variable is set, the `${work_dir}/pubkey.gpg` file will not exist. This has not caused any issue so far because the `ARCHISO_GNUPG_FD` file descriptor opens the file for both reading and writing, which means the file gets created if it does not exist. Assign the exported public key file name to a `gpg_publickey` variable in `_export_gpg_publickey` and check for it when the file is used. Since the exist status of the gpg command cannot be checked, look for the exported public key file instead.
