Cygwin: wincap: split has_posix_file_info 

While FileRenameInformationEx is defined starting with Windows
10 1709 per MSDN, it only starts working in W10 1809, apparently.
Users of 1803 report "Function not implemented".

Introduce wincap_10_1809 and change the version check in
wincapc::init accordingly.  Split has_posix_file_info into
has_posix_unlink_semantics and has_posix_rename_semantics.
Enable the latter only starting with W10 1809.
