Add missing signature algorithms for awskms

Although it was already possible to sign using RSA or RSA-PSS with
SHA384, it wasn't possible to use the appropriate signing algorithms to
create the RSA key. This commit adds those to the map.

This commit also fixes a typo and a linter error in mackms.
