[PATCH] bootstrap: fallback to wget for downloading .po files via a proxy

[Voelker, Bernhard]

Maybe a post-8.13 issue:

Since 2c57c49cc39e8e7250495d4d7ce713ba06272a46, bootstrap
fails downloading the .po files when behind a firewall,
because rsync does not allow a proxy server to be set -
well, at least my proxy server refuses to work together
with rsync's RSYNC_PROXY environment variable.

Here's a patch for falling back to wget when rsync fails.
A word to bandwidth: the --mirror option takes care about
downloading only changed files.

* bootstrap (download_po_files): Fallback to wget when downloading
the .po files via rsync failed. This is necessary to bootstrap behind
a strict firewall.
