Backport Install efibootmgr before updating Ubuntu OS packages

This step is needed to unblock the ubuntu18 arm  build
that is failing during the update of the `grub-efi-arm64` with the error:
```
Setting up grub-efi-arm64 (2.04-1ubuntu47.4) ...
Installing for arm64-efi platform.
grub-install: error: efibootmgr: not found.
```
This is a known issue: https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1936857

The discarded alternative is to exclude some packages from the update:
```
sudo apt-mark hold grub-efi-arm64 grub-efi-arm64-bin grub-efi-arm64-signed
```
