mkimage: Fix variable length header support

Browse Source 
Support for variable length images like AIS image was introduced
in commit f0662105b6. A parameter
"-s" was also introduced to prohibit copying of the image file
automatically in the main program. However, this parameter
was implemented incorrectly and the image file was copied
nevertheless.
