Reviewed by Darin Adler.

This is a rework of the patch proposed on
https://bugs.webkit.org/show_bug.cgi?id=219572

GNU/Hurd does not define an arbitrary PATH_MAX limitation.

- Constructed paths can be allocated as appropriate.

- For realpath() calls, since posix 2008 and since long on bsd/linux-like
OS, realpath() can be passed NULL.

* Source/JavaScriptCore/API/tests/testapi.c:
(main): Pass NULL to realpath().
* Source/WTF/wtf/playstation/FileSystemPlayStation.cpp:
(WTF::FileSystemImpl::listDirectorySub): Compute buffer size.
(WTF::FileSystemImpl::realPath): Pass nullptr to realpath().
* Source/WTF/wtf/posix/FileSystemPOSIX.cpp:
(WTF::FileSystemImpl::openTemporaryFile): Compute buffer size.
* Source/WebCore/platform/text/hyphen/HyphenationLibHyphen.cpp:
(WebCore::scanDirectoryForDictionaries): Use FileSystem::realPath().
