libcamera: pub_key: Gracefully handle failures to load public key

If the public key fails to load, PubKey::isValid() function returns
false. The only user of the PubKey class, the IPAManager class, doesn't
check that condition, and still calls the PubKey::verify() function,
which leads to a crash.

Fix this by returning false from PubKey::verify() if the key isn't
valid, and log a warning in the IPAManager constructor to report the
issue.
