BZ: 1910267
BRANCH: rhel-8.4.0
BREW: 33929331

When qemu-ga was introduced to RHEL-8, we used the qemu-guest-agent
from RHEL-7 as base.

In RHEL-7, qemu-guest-agent is built as standalone package.
It's built as "qemu-ga", hence the "qemu-ga" folders.

For RHEL-8, that should have been renamed to qemu-kvm, but I missed it.
Renaming those folders to /etc/qemu-kvm is a no go today, because
users might have populated the /etc/qemu-ga/fsfreeze-hook.d folder.

So, in order to make qemu-ga -F works in RHEL-8, a link is being
created in the expected place, pointing to the real one.

Also, fsfreeze-hook opens up the fsfreeze-hook.d on the same PATH where
it is stored. However, it doesn't follow symlinks. In order to fix this,
I had to change it to make sure it follows the link.

An option would be to also link the fsfreeze-hook.d folder, but I choose
not to do so as it creates a permanent/visible change in users
environments. The downside is to keep another downstream-only change.
