[PATCH] fetch2: Handle errors orruring when building mirror urls

[Richard Purdie]

When we build the mirror urls, its possible an error will occur. If it
does, it should just mean we don't attempt this mirror url. The current
code actually aborts *all* the mirrors, not just the failed url.

This patch catches and logs the exception allowing things to continue.
