Subject: [PATCH 1/2] netrw: Fix gx command

Fix #4738.
Since Netrw v165, the gx command had been broken at least on macOS and
MS-Windows. The platform-specific open commands support to handle a
remote URL directly, however, Netrw downloaded a file first.

Stop downloading a remote file when the viewer supports to handle a
remote URL.
