libcamera: Make IPA module signing optional
The IPA module signing mechanism relies on openssl to generate keys and
sign the module. If openssl is not found on the system, the build will
fail. Make the dependency optional by detecting openssl, and skip
generation of signatures if openssl isn't found.
