build: guard free_locales with HAVE_WORKING_LIBINTL #19095

With 4c7462fdb313a64d6903809ece2d8d564c0ea420, when `libintl` is turned off via
`-DENABLE_LIBINTL=OFF`, Neovim does not compile in Debug mode with the following
error message:

```

The previous commit, b1b58020094a2ffa85e40194b8beb2945396610a, to 4c7462f does
not have this issue. As you can see in the following, the issue occurs only in
Debug mode with `libintl` turned off:

```bash
# No issue
git checkout b1b5802

# The following Debug build works
make distclean; make SDKROOT=$(xcrun --sdk macosx --show-sdk-path) CMAKE_EXTRA_FLAGS="-DENABLE_LIBINTL=OFF"
# The following Release build works
make distclean; make CMAKE_BUILD_TYPE=Release SDKROOT=$(xcrun --sdk macosx --show-sdk-path) CMAKE_EXTRA_FLAGS="-DENABLE_LIBINTL=OFF"

# Compile error when in Debug and libintl turned off
git checkout 4c7462f

# The following Debug build does not work
make distclean; make SDKROOT=$(xcrun --sdk macosx --show-sdk-path) CMAKE_EXTRA_FLAGS="-DENABLE_LIBINTL=OFF"

# The following Debug build works
make distclean; make SDKROOT=$(xcrun --sdk macosx --show-sdk-path)

# The following Release build works
make distclean; make CMAKE_BUILD_TYPE=Release SDKROOT=$(xcrun --sdk macosx --show-sdk-path) CMAKE_EXTRA_FLAGS="-DENABLE_LIBINTL=OFF"
```

I noticed this because I turn `libintl` off when compiling `libnvim` for VimR.

Fix #19093
