main/syslinux: Changed update-extlinux to detect intel-ucode
If `/boot/intel-ucode.img` is present, update-extlinux will add it as
(first) INITRD. This way the microcode update in package non-free/intel-ucode
will be automatically loaded, if installed. This package fixes, among other
processor bugs, the hyper-threading bug in Intel Skylake and Kaby Lake
processers currently in the news [1]. More details here [2] and here [3].
