Please unblock package intel-microcode

Unfortunately, both amd64-microcode and intel-microcode can trigger a very
nasty bug in initramfs-tools that renders the initramfs unusable, and
therefore may make the system unbootable.

It will only happen when initramfs-tools is incapable of creating ORDER
files (e.g. because of noexec $TMPDIR or noexec /tmp with $TMPDIR unset),
so it should be pretty rare.  But still, the consequences are dire...
kinda like some of the processor errata the packages fix, I suppose :-)

This has bitten an user of intel-microcode.  Please refer to bug #689301
and #688794.

This upload works around the bug in initramfs-tools, which is the safest
way to go about it (especially considering backports).

It also fixes the previous microcode update(!): Intel did a very strange
upstream release, even naming the microcode bundle "v2", which they had
never done before.  They added microcode for seriously enterprise-class
hardware (Xeon E7) and updated again the same microcodes they had updated in
the previous release (for very widely used i5 and i7/Xeon E5 processors).

The file removals (see difstat) are a safe reduction of the size of the
*source* package, and don't change *anything* on the binary packages (I have
triple-checked this), as all microcodes in those files were superseded.

Cleaned up debdiff attached (without the microcode-*.dat hunks), because the
full debdiff is ~10MiB due to the file removals.

sorry, I mentally took them for references to the bugs in the packages.
That mail should then have been sent to the two bugs instead of d-release.

Both are now unblocked, thanks for your work!

Kind regards
