[PATCH] gnulib-tool: Fallback to wget when rsync fails

[Mathieu Anquetin]

Current implementation only tries to rsync PO files when rsync is
installed on the host. In case of error, no files are downloaded even
if they are available. This leads to bootstrap problems for hosts
that lie behind a restrictive firewall.

This patch always tries to rsync by default, falling back to wget if
an error occurs.
