linux-firmware: package all ibt-17-x-x.sfi/ddc firmware

All ibt-17-x-x.sfi/ddc firmware are use to support Intel Bluetooth 9560
they are needed in different version of Bluetooth driver since
4.14 kernel version.

commit b77bb7afe513 ("linux-firmware: package ibt-17-16-1 firmware")
only package one of the ibt-17 series firmware.

As the Bluetooth driver's update, to avoid packaging the ibt-17 firmware
one by one, install them in one package ibt-17.
