Implement support for passing the curve id via the --curve-id
option. Default assumes secp256r1. secp384r1 is also supported.

and environment variables. Adapt a test case to exercise this new
functionality.

Gnutls supports TPM 1.2 keys in its API and we can use a TPM 1.2
signing key for signing the EK or platform certs.

In case of a TPM 2 we allow the creation of a signing key by passing
--allow signing. To also enable key encipherment, we add the --decryption
option to allow key encipherment and signing at the same time.

TPM2 allows the primary key to also be a signing key, so in case
--tpm2 is provided, --allow-signing can be provided as well in
case the primary can also be used for signing operations.
We use SHA256 for the signing algorithm when TPM 2 is being used.
