Adopt square/go-jose for JWT support 

Replace uses of go-oidc/jose with square/go-jose. The v3 release
of go-oidc does not support any general-purpose JWT APIs and uses
square/go-jose internally.

This removes the dependency on the master version of go-oidc, which
fixes fatal module import problems when importing cloudflared as a module.

This fixes #592
