[PATCH gnupg 2/2] build: Check for the IBM TSS tools to run the tpm2d tests.

* configure.ac (TEST_LIBTSS): Make that conditional depend on the
detection of tssstartup.

While the tpm2d daemon can use either the Intel TSS or the IBM TSS,
the test code (specifically, the start_sw_tpm.sh script) requires
some tools from the IBM TSS (tssstartup and tsspowerup).

If a software TPM is detected at configure time but the IBM TSS
tools are absent (e.g. because only the Intel TSS is available on
the system), `make check` will attempt to run the tpm2d tests and
those will fail when the start_sw_tpm.sh script is launched.

This patch makes running the tpm2d tests dependent not only on
the detection of a software TPM, but also on the detection of
tssstartup (it is probably safe to assume that if tssstartup is
present, then tsspowerup is available as well).
