examples/performance-thread: fix return sign

Browse Source 
The patch fixes an inverted return value in the
cond_destroy and cond_init APIs of the pthread shim
example.

These APIs are now demonstrated in the sample app by
having the mutexes and condition variables
explicitly destroyed before the appplication terminates.

Fixes: 433ba6228f9a77a9b5f4 ("add pthread_shim app")
