[PATCH 1/2] binman: Tweak implementation of fmap

[Simon Glass]

Use an interator in two of the fmap tests so it is easier to add new
items. Also check the name first since that is the first indication
that something is wrong. Use a variable for the expected size of the
fmap to avoid repeating the code.
