    Install which on Fedora

    Create an install hook where core utilities can be installed
    on Fedora. In this case we are installing which.
    Which is being used by
      ramdisk/post-install.d/01-ensure-binaries
      vm/finalise.d/51-grub
    The absence to which caused the ramdisk build to fail on F19.

    On Ubuntu which is installed with the package debianutils, this pretty
    much has to exist on Ubuntu images, so a corresponding package install for
    ubuntu isn't needed.

    Fixes Bug 1202612
