Add a "--disable-pygrub" option for being able to disable the build and installation of pygrub. There are two main reasons to do so: - A main reason to use pygrub is to allow a PV guest to choose its bitness (32- or 64-bit). Pygrub allows that by looking into the boot image and to start the guest in the correct mode depending on the kernel selected. With 32-bit PV guests being deprecated and the possibility to even build a hypervisor without 32-bit PV support, this use case is gone for at least some configurations. - Pygrub is running in dom0 with root privileges. As it is operating on guest controlled data (the boot image) and taking decisions based on this data, there is a higher security risk. Not being possible to use pygrub is thus a step towards a reduction of attack surface. Default is still to build and install pygrub.
