Subject: [PATCH] tests: auto-set LIB_HTTPD_PORT from test name

We set the default apache port for each of the httpd tests
to the 4-digit test number of the test script. We want these
to remain unique so that the tests do not conflict with each
other when run in parallel.

Instead of doing it manually in each test script, let's just
set it from the test name at run time. This is simpler, and
is one less thing to be updated when test scripts are
renamed (e.g., when being re-rolled or when conflicting
after being merged with another topic).

Incidentally, this fixes a case where t5537 and t5538 used
the same port number (5537), and could conflict with each
other when run in parallel.
