Currently the grub2 package contains both all the grub binaries and configures
the system to use grub as the bootloader. As such it correctly conflicts with
sdbootutil-rpm-scriptlets, causing failures when trying to install grub2 on a
system with systemd-boot already installed.

I want to be able to install the grub binaries without configuring the system
to use grub as the bootloader. So please introduce a subpackage grub2-bin or so
that contains all the grub binaries (everything from grub in /usr/bin) so that
the grub binaries can be installed independently from making the system use
grub as the bootloader.
