wic/rawcopy: Support files in sub-directories
If the source file is located in a subdirectory of DEPLOY_DIR
rawcopy will currently fail in sparse_copy function on
open(dst_fname, 'wb'), as the parent directory for destination
file does not exist.
This patch helps to avoid that by recursively creating
parent directories.
