### Godot version

any version after 74458b6

### System information

Linux x64, but likely irrelevant

### Issue description

OpenXR action maps are not properly exported in recent builds of Godot 4: the `.res` file is small and does no longer seem to contain anything of use. In-game, no actions are passed on to OpenXR (obviously).

I bisected the issue down to https://github.com/godotengine/godot/commit/74458b6e9bed0f28db3374c7406eacbcf4b09b9d, which was merged in #70377.

### Steps to reproduce

1. Delete any previous export files (`.godot/exported/*/*.pkg`)
2. Perform an export (I did one for Android, but it likely works with anything)
3. Observe OpenXR actions not working in the export (error spam 'sync_action_sets: Condition "active_sets.size() == 0"'), and the exported action map file being very small (`.godot/exported/*/*.pkg`, from a few tens of kilobytes down to 296 bytes)

### Minimal reproduction project

Any OpenXR project can be used, such as https://github.com/BastiaanOlij/godot4_openxr_demo
zipWriteInFileInZip(p_zip, target.utf8().get_data(), target.utf8().size());
			zipCloseFileInZip(p_zip);
		} else if (da->current_is_dir()) {
			zip_folder_recursive(p_zip, p_root_path, p_folder.path_join(f), p_pkg_name);
		} else {
			bool _is_executable = is_executable(dir.path_join(f));
			OS::DateTime dt = OS::get_singleton()->get_datetime();
			zip_fileinfo zipfi;
			zipfi.tmz_date.tm_year = dt.year;
			zipfi.tmz_date.tm_mon = dt.month - 1; 
			zipfi.tmz_date.tm_mday = dt.day;
			zipfi.tmz_date.tm_hour = dt.hour;
			zipfi.tmz_date.tm_min = dt.minute;
			zipfi.tmz_date.tm_sec = dt.second;
			zipfi.dosDate = 0;
			
			
			
			uint32_t _mode = (_is_executable ? 0100755 : 0100644);
			zipfi.external_fa = (_mode << 16L) | !(_mode & 0200);
			zipfi.internal_fa = 0;
