factory_install: Call chromeos-tpm-recovery to reset TPM.
Factory Reset shim has to clear (wipe/zero) TPM NV spaces so devices
with wrong antirollback records can be recovered. However, the script
becomes more complicated due to (1) vboot changes (2) TPM2.
vboot_reference has an utility 'chromeos-tpm-recovery' that was has
more complete support of TPM recovery, although it does more (try to
re-create or even redefine the space) than what we need. To prevent
duplicating code, we should just run chromeos-tpm-recovery instead of
introducing our own implementation.
BUG=chromium:664390
TEST=./build_image factory_install; boot as recovery mode on Link+TPM1,
enter menu, select item "r" (Reset) or "i" (Install). Also tried
on Reef+TPM2.
