mkimage can be used for both signing the FIT or encrypt its content and the option '-k' can be used to pass a directory where both signing and encryption keys can be retrieved. Adding 'fit,encrypt' property to the 'fit' node, leads to try to find keys directory among binman include directories. _get_priv_keys_dir() is renamed as _get_keys_dir() and adapted to support both signing and encryption nodes in the FIT.
