lib/flashrom_drv.c: Handle empty regions array correctly.
flashrom_write_image() branches on whether specific regions have been
requested: if no regions are requested, then the layout is left as the
default, resulting in the whole image being selected; otherwise, only
the specified regions are selected. However, currently there is an edge
case of specifying a non-null, but empty array for regions; this results
in the regions codepath being taken, but no regions being selected,
resulting in a no-op.
Update the condition to treat an empty array the same as a null array,
resulting in the whole image codepath being taken for default EC
updates.
