bootm: update image OS image size when decompressing

Browse Source 
In bootm_load_os() the OS image is decompressed. In later stages of the
boot process we need the decompressed size of the image.

Update images->os.image_len after decompression.

Passing the correct size is necessary if we want to check loaded EFI
binararies for file truncation by comparing the loaded size to the header
field SizeOfImage.
