Create directories for extraction with mode 0700 - #152

If `APPIMAGE_EXTRACT_AND_RUN` is set, the AppImage will be extracted to a directory in `/tmp`, which is world-readable. If the extraction directory is created with mode 0755, this means all users on the system can read the extracted AppImage contents, which is an unnecessary information disclosure on multi-user systems. Creating the directory with mode 0700 avoids this.
