pyflashbmc: Remove initramfs from list of expected images

Remove the no longer present initramfs image as the initramfs
is no longer stored in a seperate partition.

Individual flash partition updates have not worked via rest (Update will
return "Unpack Error") since the switch to storing the initramfs in the
FIT image.
