Check and init command ignore YAML options

[Chostakovitch]

When running autorestic check, at some point, autorestic runs restic check. However, any option in the YAML configuration file won't be passed to restic. Only environment is included. The code is here : https://github.com/cupcakearmy/autorestic/blob/3bc091f826704d0a95d4d500d60083bddd3dee74/internal/backend.go#L122-L124

A few lines later, restic init won't use YAML options neither.

Example configuration file:

backends:
   rest:
   [...]
    options:
      all:
        cacert:
        - /var/lib/restic/certs/ca/ca_cert.pem
        tls-client-cert:
        - /var/lib/restic/certs/client_cert_with_key.pem

In that case TLS options are ignored and the command fails with an unknown certificate error.
