Clean up server-tests.php remains

sapi/tests/ has been introduced as a generic means to test different
SAPIs[1].  run-tests2.php has later be renamed to server-tests.php and
recently been dropped[2].  However, the sapi/tests/test00?.php test
cases remained, even though they make no sense for run-tests.php,
since they use an unsupported format for the `--ENV--` section and the
completely unsupported `--HEADERS--` section, respectively.  While
these tests ran successfully under run-tests.php, that was only by
accident, and they did not really test something useful.  Therefore, we
remove these tests altogether.

sapi/tests/bug69487.phpt is actually a CGI test (CGI is enforced due to
the `--POST--` section), so we move it to sapi/cgi/tests, which leaves
sapi/tests/ empty.  Thus, we also remove the sapi/ directory from
run-tests.php.

Finally, we remove the `--HEADERS--` and `--REQUEST--` sections from
the list of allowed run-tests.php sections.
