meta-agl-core: systemd: Disable `BitRate` setting for `can*` network for VIRTIO.

VIRTIO CAN [1] does not support bitrate configuration, it assumes
bitrate configuration is done on backend.

Fixes systemd-networkd failure:

    can0: Failed to set CAN interface configurations: Operation not supported

File `canbus-virtio-can.network` is copied from `canbus-can.network`
with `BitRate=` setting removed.

v2: rework patchset to use own systemd-conf-canbus package to
    avoid changes in main systemd package.
