Hanno Becker 895c5ab88e Preserve old behavior by checking public key in RSA parsing function ...

The function `pk_get_rsapubkey` originally performed some basic
sanity checks (e.g. on the size of public exponent) on the parsed
RSA public key by a call to `mbedtls_rsa_check_pubkey`.
This check was dropped because it is not possible to thoroughly
check full parameter sanity (i.e. that (-)^E is a bijection on Z/NZ).

Still, for the sake of not silently changing existing behavior,
this commit puts back the call to `mbedtls_rsa_check_pubkey`.
