[yocto] [meta-raspberrypi][PATCH] sdcard_image-rpi.bbclass: Fix do_image_rpi_sdimg tashhash mismatch

[Jonathan Liu]

IMAGE_CMD_rpi-sdimg() uses the IMAGEDATESTAMP variable, so the taskhash
of the function keeps changing. This results in a taskhash mismatch
error.

Fix this by excluding the IMAGEDATESTAMP variable from the checksum.
