loader: Allow image header bigger than 1 KB for encrypted images

boot_copy_region() was written so it assumes that the image header
must fit int the intermediary buffer of 1 KB size. A bigger header
will cause a overflow in calculation of size of data chunk to be
decrypted.

This patch allow to use header bigger than that buffer size and
mitigate the limitation described above.
