Reopen log file in addition to reading conf file when vswitchd receives sighup

This only reopens the vswitchd log file.  The child secchan processes
for each bridge are not requested to do the same thing.  Since secchan
in general logs very little data, rotating those files isn't being
done right now, so this is probably okay.  At some point we should
probably correct it however.
