[PATCH 3/3] compat/posix: drop legacy <utime.h> header and shims

["Alexey Samsonov via GitGitGadget" <gitgitgadget@gmail.com>]

From: Alexey Samsonov <vonosmas@gmail.com>

With all callers across the codebase now converted to utimensat(2), we no
longer need to include the legacy <utime.h> header in `compat/posix.h`.

Remove `#include <utime.h>` from `compat/posix.h` and test fixtures,
remove `mingw_utime()` from `compat/mingw.c`, and delete the legacy
header shims in `compat/vcbuild/include/`.
