Ensure pgrep only picks virt-launcher pid while collecting nft rules

[nijinashok]

The must-gather will fails to collect nft rules of virt-launcher pods
running in the same node where the must-gather is running because it
picks also the oc exec virt-handler pgrep pid. This patch ensures that pgrep only picks virt-launcher pid.

Hi @nijinashok. Thanks for your PR.

I'm waiting for a kubevirt member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
