[syslinux] using Lua to check gPXE extensions

[Alexandre Blanchette]

I saw Geoff Lywood's patch to check gPXE functionnality, it is very
interesting. Would it make sense to make add the gPXE availability flag
inside the Lua interpreter? In my case, I would use it to detect if I can
boot Windows PE the old-fashioned way by tftp or if I can download an ISO by
http and boot it with memdisk.
