Install tests

[elmarco]

Allow tests/ to be installed and run from the system.

The installation path is loosely based on https://wiki.gnome.org/Initiatives/GnomeGoals/InstalledTests guidelines. We don't provide the .test files though, at this point. Instead, I wrote a simply installed-runner.sh script which mimics autotools basic runner. (ideally, the tests could use TAP instead etc)

Missing:

• [ ] running with SWTPM_TEST_EXPENSIVE=1
• [ ] SWTPM_TEST_STORE_VOLATILE=1
• [ ] SWTPM_TEST_IBMTSS2=1
• [ ] and sudo

I think the current patch set should be ok for review/merge though.

The problem with the pkcs11 test failing seems to be due to the PATH being set in the test case not pointing to the correct directory anymore. It looks like this:

• PATH=/src/swtpm_cert:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin

If you remove SWTPM_EXE from being set in test_tpm2_vtpm_proxy, test_vtpm_proxy, test_tpm2_save_load_state_2, test_tpm2_save_load_state_3 (and SWTPM_IOCTL from latter two) as well as a few others, then these work in the installed case with sudo. SWTPM_TEST_EXPENSIVE=1 ./installed-runner.sh seems to already do what it is supposed to.

Can you squash all the 'teach' patches?

Yes I plan to do the rest as follow-ups
