tools/rtla: Add unit tests for utils.c

Browse Source 
Add unit tests for utility functions in src/utils.c using the Check
testing framework. The tests verify parse_cpu_set(), strtoi(), and
parse_prio() functions.

Unit tests are built conditionally when libcheck is available.
Run tests with 'make unit-test'.

The test framework uses the Check library which provides process
isolation for each test, preventing failures in one test from
affecting others.
