lib: tests: Add test for spinlocks

Browse Source 
Implement the test which covers some of the functions from the
`riscv_locks.h` file. This test consists of 3 test cases:

1) For lock/unlock functions
2) Unsuccessful trylock (the lock was previously taken)
3) Successful trylock (the lock is free and can be taken)
