futility: add support for .pem with public keystabilize-smaug-7566.B

Add support for PEM file containing a RSA Public key in futility "show"
and "create" commands.

When "futility create" is given a PEM file with only a RSA public key,
generate the proper .vbpubk2 rather than failing.

BRANCH=smaug
BUG=none
TEST=make runtests
and run manually
