test(tests): port setUp/tearDown as set_up/tear_down with TearDown

Port PHP setUp/tearDown across the ported integration tests using
same-named set_up()/tear_down() functions and a TearDown struct whose
Drop runs tear_down(). Fixture-init setUp returns its fixtures;
tmpdir-style setUp/tearDown carry state in TearDown fields. Parts that
depend on unported infrastructure (PHPUnit mocks, Config::merge, the PHP
error handler) stay todo!() and are only wired into ignored stubs to
avoid breaking live tests.

Also fix shirabe-php-shim putenv to handle the no-'=' form (PHP unsets
the variable), which Platform::clear_env relies on for the env-clearing
tearDowns.
