Cygwin: Makefile.in: Improve dependency for version info 

The version info only depends on the object files.  This results
in the version info not being rebuild immediately if a source
file is changed.  Rather, the version info is only rebuilt on the
next make run.

Fix that by making the version info build rule dependent on the
source files.
