rGf1163b9436b7: loader.efi: For ipxe booting, fall back to md when ramdisk fails

Summary

Some UEFI firmwares do not contain the RamDisk protocol. When this
happens, load the file into a md disk instead. This is less desireable
than the RamDisk (since that allows better chain-booting options), but
sufficient to boot an image as a md device for FreeBSD. While most
severs have the RamDisk protocol enabled in their builds, I have two
IoT class boards from different manufacturers that do not. Since it
works just fine with this fallback, that's preferable.
