bitbake: fetch2/wget: attempt checkstatus again if it fails

Some services such as SourceForge seem to struggle to keep up under load, with
the result that over half of the autobuilder checkuri runs fail with
sourceforge.net "connection timed out".

Attempt to mitigate this by re-attempting once the network operation on failure.
