* grub-install: cherry-pick patch from grub-devel to make grub-install
fault tolerant. Create backup of files in /boot/grub, and restore them
on failure to complete grub-install. LP: #1891680
Also cherry-pick patch to make atexit work correctly.
* postinst.in: do not exit successfully when failing to show critical
grub-pc/install_devices_failed and grub-pc/install_devices_empty
prompts in non-interactive mode. This enables surfacing upgrade errors
to the users and/or automation. LP: #1891680 LP: #1896608
* postinst.in: do not attempt to call grub-install upon fresh install of
grub-pc because it it a job of installers to do that after fresh
install. Fixup for the issue unmasked by above. LP: #1891680
* postinst.in: Fixup postinst.in, to attempt grub-install upon explicit
dpkg-reconfigure grub-pc. LP: #1892526
