qtest: Move tpm_util_tis_transmit() into tpm-tis-utils.c and rename it

To be able to remove tpm_tis_base_addr from test cases that do not really
need it move the tpm_util_tis_transmit() function into tpm-tis-utils.c and
rename it to tpm_tis_transmit().

Fix a locality parameter in a test case on the way.
