To find the latest patch release of a minor version, for example
`rclone selfupdate --version 1.75`, selfupdate searched the listing of
downloads.rclone.org for href="./vX.Y.Z/". The leading ./ is a detail
of how Caddy's file server writes its links. A listing which linked to
the same directories as "vX.Y.Z/", which is an equally valid relative
URL, made selfupdate fail with "could not find the minor release".
This makes the ./ optional in the pattern, so selfupdate no longer
depends on which program wrote the listing, and takes the version from
a capture group rather than from fixed offsets into the match.
The listings written by rclone index now include the ./ for the
benefit of rclone versions without this fix, so this is to remove the
dependency for the future.
