    Revert the workarouds for kernel override

    Centos 7.5 is released with the new kernel so workaround applied
    for Centos 7.4 update kernel needs revert.
    The patch reverts the following 4 commits applied
    in order to override kernel. Some nested VMs(Skylake) have
    issues running virt-customize with kvm backend, so set
    LIBGUESTFS_BACKEND_SETTINGS=force_tcg to not use
    kvm accelaration. Setting this option drops performance
    for running virt-customize a little but can't find any other
    option until it's fixed in kernel/kvm.

    Revert "add option to turn on/off non default kernel"

    This reverts commit fec6fd069d074a73304c3e0498a00855df2fa4c4.

    Revert "Do not attempt install kernel when chrooted"

    This reverts commit d991c1033f3a6390720210d682e3c155959bbe71.

    Revert "Ensure libguestfs_kernel_override kernel is installed"

    This reverts commit ff0a5c9ac7149e89da2c01a8e184004bb536d43e.

    Revert "Set SUPERMIN_* variables to working kernel"

    This reverts commit 6aac21081db4054b71257c396823b9af1d760311.
