[LTP] [PATCH 3/3] kmsg01: use lower timeout for test_read_block()

[Jan Stancek]

Test is currently expecting that read will block for ~5 seconds.
This is a problem for busy systems, where there are many messages
periodically generated. One example is ie31200_edac module,
which periodically generates a message every second on debug
kernels.
