The load file implementation added by commit
c7c3d839fc9120aee28de9aabe452dc85ad91502 doesn't support loading
arbitrary files from the tftp server, so efi applications trying
to do exactly that fail to boot:

This is not acceptable for qemu. efi pxe configurations which work
just fine with real hardware must work with qemu virtual machines too.
This patch adds a config option for the load file protocol
implementation, to allow it being disabled, so we can turn it off
for the pxe roms shipped with qemu.
The default for the new option maintains current behavior, i.e.
load file is enabled unless you override it in config/local/general.h
