tpm_lite_stub: clean up debug printouts in VbExTpmSendReceive
1) Callers of VbExTpmSendReceive often use the same buffer for
TPM command and response. So, debug-print the command before
sending to avoid it being overwritten with the response before
printing.
2) VbExTpmSendReceive only prints execution time in debug mode.
Execute gettimeofday() only when debug mode is enabled.
3) Avoid printing "DEBUG: " prefix before every byte in the
command/response.
BUG=none
BRANCH=none
TEST=emerge-$BOARD vboot_reference with and without DEBUG=1,
run tpmc commands, check the output.
