rngd: don't open the TPM if hwrng is available

If /dev/hwrng is avaiable, do not open the TPM.  Newer kernels export
TPM randomness via /dev/hwrng; this properly handles multiplexing of
the TPM so that we don't interfere with TrouSerS.  Thus, we don't want
to open /dev/tpm0 if we can open /dev/hwrng.
