[prefix] Allow iPXE's own command line to be executed as a script
Some prefixes (e.g. .lkrn) allow a command line to be passed in to
iPXE. At present, this command line is ignored.
If a command line is provided, treat it as an embedded script (without
an explicit "#!ipxe" magic marker). This allows for patterns of
invocation such as
title iPXE
kernel /boot/ipxe.lkrn dhcp && \
sanboot iscsi:10.0.4.1::::iqn.2010-04.org.ipxe.dolphin:storage
Here GRUB is instructed to load ipxe.lkrn with an embedded script
equivalent to
#!ipxe
dhcp
sanboot iscsi:10.0.4.1::::iqn.2010-04.org.ipxe.dolphin:storage
This can be used to effectively vary the embedded script without
having to rebuild ipxe.lkrn.
