Make sequoia signing work with sequoia-sq >= 0.38

sequoia-sq 0.38 removed all short options, at least temporarily:
https://gitlab.com/sequoia-pgp/sequoia-sq/-/commit/f7ce1fa2a172ae02171a3421bebf2a4aa3cfb8a5

There's no reason why we couldn't use the long ones though, it's more
readable that way anyhow. Shrug and move on.

Fixes: rpm-software-management#3317
