Using swtpm v0.7.0 we can run swtpm_setup to create default config files

command line before. This program needs to run once.
This patch addresses the issue raised in
https://bugzilla.redhat.com/show_bug.cgi?id=2010649
BTW, I notice the this tool creates certs under $HOME/.config/var
with an expiry date of +10 years.
Now that sounds like a long time, and indeed it is a long time,
but then I look at the support lifetime of RHEL... Hopefully
bare metal hardware won't last for the whole 10 years without
being replaced, but with nested virt the "hosts" could be VMs
that get moved to new hardware.
So what's the story if a host hits the 10 year mark for the
swtpm certs ? Presumably swtpm is validating these dates
and will refuse to launch the TPM for the VMs on the host ?
It doesn't.
