update/improve intel-microcode and iucode-tool

Patch 1 enables MICROCODE_INTEL if intel-microcode is selected, since otherwise it's impossible to load microcode (by means of iucode-tools).

Patch 2 updates intel-microcode to the latest version and moves its installation path from /usr/share/misc/ to /lib/firmware/, along with the files installed by linux-firmware. That path is also used by other Linux distros (e.g. Ubuntu). Notice that the package now installs 100 binary files under /lib/firmware/intel-ucode/ instead of a big text file at /usr/share/misc/intel-microcode.dat.

Patch 3 updates iucode-tool to the latest version.

Patch 4 updates the iucode-tool init script. That's what I was doing initially. All other patches are just a consequence ot the "plucking a feather brings a hen" effect.

Patches 1, 2 and 3 can be applied in any order (I tested this) but patch 4 is on top of patch 2.
