In order to write the grub configuration and perform the preliminary
checks, the grub-mkconfig command should run in the bootloader_t domain.
As such, update the file context definition to be bootloader_exec_t.
The grub2-install application runs a few grub2-* commands. Two of those,
grub2-bios-setup and grub2-probe, need read/write access to the (fixed) disks.
Mark those two applications as bootloader_exec_t (as is the case with the "grub"
legacy command in the past) allows the commands to continue.
