travis: dependency on TSS for initializing software TPM

Verifying the "boot_aggregate" requires reading the TPM PCRs for each of
the TPM banks.  In test environments without a physical TPM, a software
TPM may be used, but requires initializing the TPM PCRs.  By walking and
replaying the TPM event log, a software TPM may be properly initialized.
