libtoolize.in: Create symlinks with mklink for MSVC

Symlink files are not generated properly with 'ln -s' for MSVC to
process, so mklink is used, which swaps the argument order of target
and link_name. This also requires absolute paths, generated with the
use of cygpath.

* libtoolize.in: Check if linking with mklink and update processing.
