ic-container: qemu: Set connector name for IVI layer manaager

The ivi-layer manager configuration file needs to know the name
of display connector to set up the layer configuration.

Adjust the connector name in the configuration file to reflect
the connector names in us on the platform being built.  This
currently only applies to qemu, but could be applied to other
build configurations in future.
