* scripts/functions: include a new option to skip enslaved network
devices. (LP: #1802591)
Include the new variable NETWORK_SKIP_ENSLAVED. When set to a
value different than "0", this variable will cause any enslaved
network devices to be skipped from the list of netbootable
devices. This variable can be set via the configuration files
under /etc/initramfs-tools/ or via any configuration file under
the initrd directory /conf/conf.d/ via a hook script.
