hugepages.sh script doesn't handle start[ed]/begin hooks

[Hamled]

After upgrading to libvirt 7.0.0 (at least, the version published to Arch's community package repo on 1/20/2021) I started getting errors from the hugepages.sh script. It was trying to call functions for the start/begin and started/begin events.

I'm not sure what has changed as the libvirt docs mention those qemu events being in place for years now, and I never received these errors before.

Creating some empty functions with the appropriate names seems to be working on my machine.
