Upgrades: When upgrading via FTP, use LIST -a to detect if a file exists.

Browse Source 
`LIST` & `NLST` by default on some servers require the `-a` flag to view hidden files (ie. `.maintenance`)
Although we could simply pass the `-a` flag to `NLST`, opting to use `LIST` which we use elsewhere should mean less chance of server incompatibilities.

Props jcroucher.
Fixes #28013.
