test615: fix for Cygwin, unignore in CI

Setting a server-side file read-only by `chmod 0444` has does not
prevent overwriting it via SFTP upload (as tested in CI).

Fix it by setting its MS-DOS read-only attribute in addition. It
requires the Cygwin tool `chattr`.

Also unignore in CI.

Fixes:
```
