efibootmgr testiso test is broken

[dustymabe]

For this test (added in https://github.com/coreos/coreos-assembler/pull/2435) it's not working. Systemd complains about the unit:

[    7.228836] systemd[1]: /etc/systemd/system/verify-no-efi-boot-entry.service:10: Ignoring unknown escape sequences: "! efibootmgr -v | grep -E "(HD|CDROM)\(""

and it appears there are DVD entries in efibootmgr output today:

For reference, here is what it looked like in 36.20220906.1.0, which was a build from before https://github.com/coreos/coreos-assembler/pull/2435 merged:

So we need to figure out what to do with this. It appears maybe the original goal is no longer achieved.
