[PATCH] extlinux: recognize LINUX as an alias for KERNEL

[Stephano Cetola <stephano@cetola.net>]

Syslinux configs commonly use LINUX instead of KERNEL to name the
kernel image. parse_extlinux_conf() only checked for KERNEL, so a
LABEL block using LINUX left entry->kernel unset. parse_extlinux_conf()
requires a kernel path to accept an entry, so the whole extlinux.conf
was rejected instead of just the one line being ignored.

Fixes: b912fa9fc3ca ("Add support for extlinux.conf")
