iwmfw(4): fix spelling of the iwm8000C firmware.

When migrating the firmware to be installed as plain firmware files
to /boot/firmware the iwm8000C firmware lost its "fw" suffix that
iwm(4) expects.
The follow-up change to defaults/loader.conf is also consistently
missing the "fw".

Fix both places, and add the wrongly spelt version to ObsoleteFiles.inc
(entirely untested).
