- device.mk: guard the Widevine CDM PRODUCT_COPY_FILES entry with
$(wildcard ...) so a checkout that hasn't run extract-widevine.sh still
builds (the HAL dlopen()s it at runtime and degrades gracefully already).
- ramdisk/init.rpi4.rc: restore the ${ro.hardware} mount_all generalization
(matches pawlet_rpi5, which already had it — this device tree's copy was
lost when an earlier android-16.0 upstream-sync merge got reset away).
