[PATCH 2/3] test: self: jwt: add dedicated option for development_rsa2048.pem

[Ahmad Fatoum]

This test key can be useful beyond the JWT selftest, so add an option to
select it.

The key added by the option is stand-alone, i.e., it is not part of the
key ring and won't be consulted for FIT image verification.
