ktest: Add native support for syslinux boot loader 

I installed Fedora 17 which no longer supports grub v1. I worked
with grub2 for a while, but there's so many issues with it and automated
rebooting, that I decided to switch to syslinux. Instead of using
the REBOOT_SCRIPT and add customized changes to get syslinux booted,
I thought it better to make ktest aware of syslinux and add options
to simplify the use of syslinux on a target test box.

If you specify grub2, then you also need to specify both \$GRUB_MENU

If you specify syslinux, then you may use SYSLINUX to define the syslinux
command (defaults to extlinux), and SYSLINUX_PATH to specify the path to
the syslinux install (defaults to /boot/extlinux). But you have to specify
SYSLINUX_LABEL to define the label to boot to for the test kernel.
