[Buildroot] [PATCH] Add syslinux installer host package

[Alexander Sverdlin]

Add host installer for syslinux bootloader which allows to pre-install
syslinux in the generated firmware images. BR2_ROOTFS_POST_IMAGE_SCRIPT
can do something like this:

	${HOST_DIR}/usr/bin/syslinux -d /syslinux/ -i ${IMGFILE}

if the rest of syslinux is installed under /syslinux inside the firmware
image.
