Incorrect permissions prevent measurement and hrtimer-prio sub-tests from Running

[schrht]

Description:

The run_auto.sh scripts have incorrect permissions, which prevented the realtime sub-tests ./func/measurement and ./func/hrtimer-prio from executing.

When executing the tests, you can see:

+ ./run.sh -t ./func/measurement

Fixes should add the missing execution permissions on the run_auto.sh scripts:

    testcases/realtime/func/hrtimer-prio/run_auto.sh
    testcases/realtime/func/measurement/run_auto.sh
