image-sig: Ensure that hashed-nodes is null-terminated
A specially crafted FIT image leads to memory corruption in the stack
when using the verified boot feature. The function fit_config_check_sig
has a logic error that makes it possible to write past the end of the
stack allocated array node_inc. This could potentially be used to bypass
the signature check when using verified boot.
This change ensures that the number of strings is correct when counted.
