binman: Correct fmap output on x86
Normally x86 platforms use the end-at-4gb option. This currently produces
an FMAP with positions which have a large offset. The use of end-at-4gb is
a useful convenience within binman, but we don't really want to export
a map with these offsets.
Fix this by subtracting the 'skip at start' parameter.
Also put the code which convers names to fmap format, for clarity.
