cext: define S_IFLNK on Python 2.7 and Windows
Before this change, building on Python 2.7 on Windows fails due to
S_IFLNK being undefined. This regression was introduced by
a32a96079e2d / D11518.
It worked on Python 3 because its pyport.h (which is included via
Python.h) contains effectively the same code as added by this
changeset.
