Subject: [PATCH] Termux borgbackup: use distutils instead of packaging

Do not remove this patch unless you know what you are doing!

We don't have module "packaging" packaged and thus cannot use it without
installing through "pip". But for stable packages we cannot use it in
postinst script to add missing dependencies.

So if you decide to drop this patch:
* Add python3-packaging to termux-packages.
* Alternatively: create a postinst deb script (pip3 install packaging)
  and move borgbackup to https://github.com/termux/unstable-packages
