Build on OS Windows fails with an "cannot delete" error

[Vest]

Hello everyone,

I was trying to build the latest version of the library on my Windows machine (Cygwin), and after I met all dependencies, I have faced an error:

thread 'main' panicked at 'cannot delete C:\work\ncurses-rs\target\debug\build\ncurses-614b448966de1353\out\chtype_size: Os { code: 2, kind: NotFound, message: "The system cannot find the file specified." }', build.rs:111:32

I am preparing a pull request with a fix.

The issue occurs, because instead of ...\out\chtype_size, the build script should delete ...\out\chtype_size.exe

This is resolved as v5.100.0.
