Small enhancements to the EFI image generation

This is a rather silly patch (and untested since I don't use EFI on the des=
ktop
I run FreeBSD on) to enhance the current EFI Fat image:

1- Enlarge the boot image to make it match the size of an older 5 1/4" flop=
py.
More space won't hurt and it seems better to use a somewhat "standard" size,
2- Set the OEM label to "MSWIN4.1". This is the recommended value in "Micro=
soft
Extensible Firmware Initiative FAT32 File System Specification":

"There are many misconceptions about this field. It is only a name string.
Microsoft operating systems don=E2=80=99t pay any attention to this field. =
Some FAT
drivers do. This is the reason that the indicated string, =E2=80=9CMSWIN4.1=
=E2=80=9D, is the
recommended setting, because it is the setting least likely to cause
compatibility problems. If you want to put something else in here, that is =
your
option, but the result may be that some FAT drivers might not recognize the
volume. Typically this is some indication of what system formatted the volu=
me."

I doubt either of these has any effect nowadays, and I won't feel offended =
if
the patch is rejected, but it may be better to adopt such changes earlier
rather than later.
