libpayload: provide missing cbfs symbol

The generic cbfs code relies on the libpayload_init_default_cbfs_media
    symbol. However, none was provided for ARM. Provide an empty
    implementation that returns an error as there is no generic way
    to locate the default cbfs media.

libpayload: place dummy_media.c in correct object list

The commit introducing dummy_media.c was placed in the
    libc object list. This wasn't correct. It should be in the
    libcbfs object list as well as guarded by CONFIG_CBFS.
