Fix random failing OutputStreamMonitorTests eclipse-platform#898

The testNullCharset() method of the OutputStreamMonitorTests randomly
fails. The cause is probably a too restrictive timeout of 1 seconds for
the significantly varying execution times of the test.
This change increases the timeout to 10 seconds.

Fixes eclipse-platform#898
