log/syslog: fix flakey test on slow hosts
Fixes issue 4467.
The syslog tests can fail if the timeout fires before the data arrives
at the mock server. Moving the timeout onto the goroutine that is
calling ReadFrom() and always processing the data returned before
handling the error should improve the reliability of the test.
