David Anderson 029be8d339 Force machines to chainload through Pixiecore's embedded iPXE.
This guarantees that we load the real OS from an iPXE with a known
featureset, rather than rely on the firmware iPXEs to be correct.

Also switch to ipxe.pxe for BIOS boots instead of undionly.kpxe.

ipxe.pxe works when you chainload from one iPXE to another, whereas
undionly.kpxe encounters some kind of poorly explained bug where
it loses the ability to configure networking.

Tested against the following configurations:
 - VirtualBox + BIOS w/ iPXE
 - VirtualBox + BIOS w/ Intel UNDI
 - VirtualBox + EFI
 - KVM + SeaBIOS w/ iPXE
 - KVM + OVMF (EFI)
 - Dell R610 + Dell BIOS/PXE

Fixes #51, fixes #52.
