Johannes Schindelin b1c8e2fbc5 msys2-runtime: expose the "deep-copy" symlink behavior via a new mode
This patch synchronizes msys2/MSYS2-packages/msys2-runtime with
msys2/msys2-runtime after merging
https://github.com/msys2/msys2-runtime/pull/16.

We specifically override Cygwin's symlink() behavior to make deep copies
instead of creating a special-crafted system file that Cygwin (MSYS2,
and only those two) will recognize as symbolic link.

The patch to override this behavior is incomplete, though: it hacks up
the WSYM_sysfile code path, which causes all kinds of problems:

- Contrary to the documentation, MSYS=winsymlinks:native won't fall back
  to creating Cygwin-style symbolic links. Instead, it (quite
  surprisingly) creates deep copies instead.

- There is no way to opt into the original Cygwin behavior because that
  code path is now dead code.

- The fact that the WSYM_sysfile code path is modified to do something
  very different from what it is intended to do means that all changes
  that Cygwin makes to that code path have to be inspected, and
  occasionally even more hacks have to be put on top, such as 44bb133,
  where we specifically had to disable Cygwin's code to try creating WSL
  symlinks before falling back to creating system files instead).

Let's fix this by introducing a proper new mode:
MSYS=winsymlinks:deepcopy. This mode is made the default so
that users should be unaffected by this PR.

Users wishing to let the MSYS2 runtime create Cygwin-style
symbolic links can ask for that by setting
MSYS=winsymlinks:sysfile.

By fixing this issue, we can now stop disabling Cygwin's WSL
symlink behavior, too: it is in the sysfile code path and
won't affect the default behavior of the MSYS2 runtime.

While at it, the indentation of the original patch is fixed,
too.
