Subject: [PATCH] `libzigc/math`: Remove straggler `rint` file in vendored
 MinGW

Seems like it was missed when implementing `rint`.

This was checked by running:

```
$ ./build/stage3/bin/zig build -p stage4 -Denable-llvm -Dno-lib

$ stage4/bin/zig build test-libc -Dlibc-test-path=<LIBC-TEST-PATH> -Dtest-filter=rint -fqemu -fwasmtime --summary line
Build Summary: 2209/2209 steps succeeded
```
