Don't exclude out-of-tree absolute symlinks in reparse point fix mode

Excluding such links may not be the expected behavior.  In addition,
Microsoft's documentation for ImageX seems to be incorrect when it states
that ImageX excludes such links.  Actually, it does not.  So, for the
sake of consistency and also doing something that may more sense anyway,
just retain such links, but leave their targets as-is.
