`glob(3)` doesn't know the virtual CWD of PHP, so we need to pass an absolute path for ZTS builds. In lack of a reusable routine, we copy the code from `glob()` and adapt as needed.
We should strip the CWD whenever we call `php_glob_stream_path_split()`, but that would require to store the value in `glob_s_t` what we cannot do for stable PHP versions since it would be an ABI break. Thus we traverse `gl_pathv`, and strip the prepended CWD there.

I think it should work. It wouldn't work for glob with braces (I actually started testing it with it to check if this still works) but glob wrapper does not pass that flag so braces cannot be used so using IS_ABSOLUTE_PATH should be reliable for identifying absolute path here.

glob(3)doesn't know the virtual CWD of PHP, so we need to pass an absolute path for ZTS builds. In lack of a reusable routine, we copy the code fromglob()and adapt as needed.In my opinion, there should be some routine (likely in zend_virtual_cwd) which makes a path absolute, but without normalization or even getting the real path (just quickly prepending the VCWD if necessary). I'm not quite convinced that we should introduce that routine for stable branches, though.
