faft-cr50: check /dev/tpm0 during reboot stress

On fizz we've seen some TPM flow control errors that result in /dev/tpm0
not getting created. This isn't necessarily a fizz specific issue. This
change adds a check for /dev/tpm0 after reboot just to see if we can
catch this issue during faft-cr50 nightly runs.

BUG=b:175650376
TEST=run on hatch and fizz
