Patch to allow permissions to be preserved as non-root

Previously we explicitly checked our uid and if it wasn't 0, set ARCHIVE_DONT_RESTORE_PERM flag. There wasn't a lot of info in the commit message and this seems like a bug. 

This commit effectively reverts ebad0294c9 and adds a test.

For my usecase, I built and tar-ed a package and wanted to untar it into a chroot as a non-root user. busybox tar removed the setuid bit so programs like `su` broke.
