Robert Maynard 6b5f2dbbfe file(REAL_PATH): resolve symlinks before '..' components ...

Previously REAL_PATH would collapse paths before resolving any symlinks
so if `..` crossed a symlink the output from `REAL_PATH` would be wrong.

It looked like REAL_PATH did this by mistake since it was a side-effect
of ensuring we had an absolute path before resolving symlinks.
