bitbake: wget.py: Add catch TimeoutError exception

We've observed TimeoutError exceptions during the sstate-cache mirror fetch,
it appears that due to the number of (invalid) files requested the remote
side is eventually dropping the connection (not closing it) which can result
in a TimeoutError exception being sent, while rate it is different from the
urllib.error.URLError or ConnectionResetError.
