sdcard_image-rpi.bbclass: Copy startup files required for 16MB GPU operation.

start_cd.elf and fixup_cd.dat are required when running the system with
a 16MB GPU memory configuration.  This change copies all files contained
in bcm2835-bootfiles instead of cherry picking.

sdcard_image-rpi: Use the size of the generated rootfs

When constructing the SD card image, the code was using
the inherited ROOTFS_SIZE, which is the size of the
rootfs contents. When building (for example) a compressed
rootfs, this allocates a partition much larger than necessary.

Instead, take the size of the generated rootfs file that is
about to be written into the generated image, and round it
up to the IMAGE_ROOTFS_ALIGNMENT size.

Fix some comments - the alignment is 4MiB, not 4KiB.

sdcard_image-rpi.bbclass: Fix error in conditional test

When the shell tests for rootfs type I was seeing "[[: not found".  I
use echo and egrep to test for the xz rootfs type to work around this
error.
