Fix thread safety attributes for TryLock functions

Browse Source 
Changed SDL_TRY_ACQUIRE and SDL_TRY_ACQUIRE_SHARED success value
from 0 to true for functions that now return bool instead of int.
This fixes false positives/negatives in Clang's thread safety analysis.

(cherry picked from commit 901173aee6)
