Warn if certificates in trusted_client_ca are not readable

[THS-on]

It seems that this just silently not loads the certificate:

rust-keylime/keylime/src/crypto.rs

Lines 783 to 790 in 2f7b3ad

	for cert in ca_certs {
	mtls_store_builder
	.add_cert(cert)
	.map_err(|source| CryptoError::X509StoreBuilderError{
	message: "failed to add certificate to X509 trusted certificate store".into(),
	source,
	})?;
	}

The culprit is not the part of the code you pointed out: it properly raises the error when the certificate fails to load. The problem is on its caller, which is probably ignoring the error.

This will probably be fixed once I finish the error handling overhaul I'm currently working on.

@ansasaki ah I see thanks for taking a deeper look.

Awesome thank you!
