From: Rafał Miłecki <ra...@milecki.pl>
Before recent change "tar" command was called with an "-f" argument
which accepts "-" for stdout output. Bring back support for that feature
with new code.
Fixes: e36cc530927c ("base-files: sysupgrade: use tar helper to include
installed_packages.txt")
Fixes: https://github.com/openwrt/openwrt/issues/14773
