CHERRY-PICK: Fix autotest support for a new TPM class directory.

Kernel TPM patches from 4.x moved /sys/class/misc/tpm0 to /sys/class/tpm/tpm0.
The last attempt to support both paths in firmware_TPMExtend failed to
differentiate between host and device operation.  Rather than add a second
device operation to check the path, simply use the wildcard to find the
right file.
This assumes (safely, I think) that the system has only one tpm0.

TEST=Confirm firmware_TPMExtend gives valid "Dumping PCRs read from device"
     data in both 3.18 and 3.14 kernels.
