demux_libarchive: normalize the stream url path

38ad1ed03b was supposed to normalize all
path names, but the path from the libarchive demuxer works differently.
We need to normalize it within the demuxer itself so you get something
like "archive://<absolute path to archive>" in the property.

Fixes #16247.
