klte-common: Update DSDS init script handling

* Importing this in init.qcom.rc, especially when not all builds
  have it is hacky. We'll have those devices install the script
  into vendor/etc/init and let init handle it automatically, just
  like the primary rild.rc script.
* Update the package name to align with the new name of the script.
