GRUB is used to boot Xen Dom0 hosts so BLS is supported there, but PV and
PVH Xen DomU guests are booted with pygrub that doesn't have BLS support.
This means that only HVM Xen DomU guests can support BLS and others need
a traditional GRUB configuration file that contains menuentry commands.
So to make the GRUB config compatible with all Xen DomU guests, don't use
the BLS snippets and instead call grub2-mkconfig to regenerate the config
on each kernel install and removal.
Even when HVM Xen DomU guests can support BLS, just disable for all DomU
so the configuration is consistent across all Xen DomU guests variants.
And also because even when an installation is made with HVM, this can be
later changed to a DomU variant that uses pygrub and doesn't support BLS.

The grubenv file is updated when grub-mkconfig is executed but on ppc64le
is used on each kernel install to re-generate the grub2.cfg file with the
updated entries. So in this case the grubenv file should not be updated.
