test: wait for the swtpm socket to appear

Browse source 
On slower/overloaded systems it may take a bit for the swtpm socket
to show up:

I: Started swtpm as PID 189419 with state dir /tmp/tmp.pWqUutuGUj
I: Configured emulated TPM2 device tpm-spapr
+ tee /var/tmp/systemd-test-TEST-70-TPM2_1/console.log
+ timeout --foreground 1200 /bin/qemu-system-ppc64le -smp 4 ...
qemu-system-ppc64le: -chardev socket,id=chrtpm,path=/tmp/tmp.pWqUutuGUj/sock: Failed to connect to '/tmp/tmp.pWqUutuGUj/sock': No such file or directory
E: qemu failed with exit code 1

Spotted regularly in the ppc64le cron job and in some Ubuntu CI/CentOS CI
pr runs [0].
