[PATCH 2/7] pxe_utils: accept "options" as synonym for "append"

[Alexey Charkov <alchark@flipper.net>]

The Boot Loader Specification [1] type #2 entry files use the keyword
"options" for the kernel command line, which corresponds to extlinux's
"append". Recognising it here lets the existing pxelinux parser ingest
BLS entries unchanged, paving the way for a BLS bootmeth that reuses
the parser instead of duplicating it.

No effect on existing extlinux/pxelinux files: "options" is not a valid
keyword in those formats, so it cannot collide with prior usage.
