binman: Make fake blobs zero-sized by default
On x86 devices having even a small amount of data can cause an overlap
between regions. For example, bayleybay complains when the intel-vga
region overlaps with u-boot-ucode:
ImagePos Offset Size Name
<none> 00000000 00800000 main-section
<none> ff800000 00000080 intel-descriptor
<none> ff800400 00000080 intel-me
<none> fff00000 00098f24 u-boot-with-ucode-ptr
<none> fff98f24 00001aa0 u-boot-dtb-with-ucode
<none> fff9a9d0 0002a000 u-boot-ucode
<none> fffb0000 00000080 intel-vga
...
It is safer to use an empty file in most cases. Add an option to set the
size for those uses that need it.
