scripts: create symlink for community base FW binary

Currently the symlink for sof-ipc4/platform/sof-basefw.ri is not
created when building a deployable build. Fix this so that
developers can create a deployable build that can be copied directly
to target from staging directory via rsync/scp as-is.

Adds new --deployable-dev-build flag to enable this feature.
