Remove triggers needed to upgrade from legacy GRUB

Browse Source 
The legacy GRUB package (grub2 < 1.99-4) had a %preun scriptlet that did a
rm -f /boot/%{name}/*.{mod,img,lst} and caused users who upgraded to grub2
to have an empty /boot/%{name} directory, leading to an unbootable system.

To workaround this, a set of %triggerun and %triggerpostun triggers were
added that backup and restore the /boot/%{name} directory. But that was an
issue in Fedora 16, almost a decade ago. These aren't needed anymore.

# grub2 < 1.99-4 removed a number of essential files in postun. To fix upgrades
# from the affected grub2 packages, we first back up the files in triggerun and
# later restore them in triggerpostun.
