shibboleth: Don't use gssapi, odbc, or macOS Apache

Ensure we use MacPorts Apache 2.4, not an older version bundled with
older macOS that will cause the build to fail.

Closes: https://trac.macports.org/ticket/73906

Also ensure gssapi and odbc aren't used opportunistically.

Remove redundant worksrcdir line.
