Gilles Peskine 63072b1f94 Only test custom-e RSA key generation when built in 
Custom-e RSA key generation is not yet supported in the test driver, and we
don't support fallback from the test driver to the built-in
implementation (even though we're testing with MBEDTLS_RSA_C). So for the
time being, only run psa_generate_key_ext test cases for RSA with a custom
public exponent when using the built-in implementation.

Add a test case to validate that psa_generate_key_ext test cases for RSA
with a custom public exponent returns NOT_SUPPORTED (rather than silently
doing the wrong thing) when not using built-in RSA (which is subtly
different from when having accelerated RSA: if both are enabled, which we
currently don't do in all.sh, then this should be supported and this is
validated by the test cases above).

This wart will be resolved when we add support for drivers with a
generate_key_ext entry point.
