Checked update-initramfs -v output to check that both amd64 and intel
microcode are installed, also checked that intel picks all microcode
packets.

Bug description:
  [Impact]
  Initramfs for MODULES=most should build with all microcodes installed

  [Test case]
  Have both amd64-microcode and intel-microcode installed, and MODULES=most set. Test generated initramfs in both amd64 and intel machines and make sure the microcodes load.

  If that's not feasible, we should at least run update-initramfs with
  -v and ensure that it says the right things:

  I: amd64-microcode: installing AMD64 microcode into the early initramfs...              
  intel-microcode: adding microcode for either all or selected Intel processor models
  [long list of microcodes]

  
  [Regression potential]
  Some tools will fail to understand the initramfs, as it now has two cpio archives prepended (e.g. lsinitramfs skips intel microcode archive, as seen in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=886424)
