package/rpi-firmware: fix config.txt installation
In commit 689b9ac439ab (package/rpi-firmware: rework boot/config file
handling), a last-minute fixup was made to handle the case where no
config.txt file was provided by the user.
However, the intermediate variable RPI_FIRMWARE_CONFIG_FILE was not used
consistently, and the old PACKAGE_RPI_FIRMWARE_CONFIG_FILE variable was
still used where RPI_FIRMWARE_CONFIG_FILE should have been used instead.
