eap-tls-common: Relax certificate chain check

Browse Source 
Relax the pre-check for local user certificate.  Before we used to check
that the CA provided (if any) was used to verify both the peer identity
and the local certificate chain.  However, there seem to be networks
that use different CAs to sign AP/Radius certificates and certificates
issued to users.

Drop the ca_certs argument from l_certchain_verify, but keep the call
there to make sure the certificate chain is indeed a chain as a sanity
check.
