package/libcamera: pipeline option 'raspberrypi' changed to 'rpi/vc4'

With upstram commit [1] (since version v0.1.0) the pipeline option 'raspberrypi'
was renamed to 'rpi/vc4'.

Change the buildroot option name from BR2_PACKAGE_LIBCAMERA_PIPELINE_RASPBERRYPI
to BR2_PACKAGE_LIBCAMERA_PIPELINE_RPI_VC4 (and add Config.in.legacy entry
accordingly) and move handling in Config.in/libcamer.mk to follow alphabetic
ordering.

Fixes:

  .../build/libcamera-v0.1.0/meson.build:3:0: ERROR: Options "raspberrypi" are not in allowed choices: "all, auto, imx8-isi, ipu3, rkisp1, rpi/vc4, simple, uvcvideo, vimc"
