rtla/tests: Limit duration to maximum of 10s 

Many of the original rtla tests included durations of 1 minute and 30
seconds. Experience has shown this is unnecessary, since 10 seconds as
waiting time for samples to appear.

Change duration of all rtla tests to at most 10 seconds. This speeds up
testing significantly.

Before:
$ make check
All tests successful.
Files=3, Tests=54, 536 wallclock secs
( 0.03 usr  0.00 sys + 20.31 cusr 22.02 csys = 42.36 CPU)
Result: PASS

After:
$ make check
...
All tests successful.
Files=3, Tests=54, 196 wallclock secs
( 0.03 usr  0.01 sys + 20.28 cusr 20.68 csys = 41.00 CPU)
Result: PASS
