util/ifdtool/ifdtool.c: Add NULL check for fmapname

Some boards (e.g. prodrive/hermes) that do not provide their own FMAP
and therefore have been generated by the build system (+ ifdtool)
experience a failure when trying to build with an IFD that contains
regions which do not have equivalent fmap names (set to NULL).

Therefore add a NULL check for the fmapname and ignore the region if we
do not have an fmapname.

Test: compile prodrive/hermes
