actions/unarchive: fix unarchive from remote url (#17126)

* actions/unarchive: fix unarchive from remote url

Currently unarchive from remote url does not work because the core
unarchive module was updated to support 'remote_src' [1], but the
unarchive action plugin was not updated for this. This causes failures
because the action plugin assumes it needs to copy a file to the
remote server, but in the case of downloading a file from a remote
url a local file does not exist, so an error occurs when the file is
not found.

* test_unarchive: fix test with wrong remote_src use

The non-ascii filenames test had improperly set remote_src=yes even
though it was actually copying the file from the local machine (i.e.
the file did not already exist remotely). This test was passing
until the remote_src behavior of unarchive was fixed in 276550f.
