[Bug 2047863] [NEW] Call grub2 to update BLS entries on RH-based distros

[Alexsander de Souza]

Public bug reported:

RHEL, CentOS, Rocky, Oracle Linux and possibly other RH derivative
distros have adopted the BLS specification [1] in recent releases.
Curtin must do a different procedure when configuring the bootloader in
such systems.

1. check if the system has BLS enabled:

  look for `GRUB_ENABLE_BLSCFG=true` in /etc/default/grub

2. if BLS is enabled, add `--update-bls-cmdline` flag to the
grub2-mkconfig command line in `curtin/commands/install_grub.py`
