SDL_systhread.c: Remove SIGCHLD from blocked signal mask.

Browse Source 
When SIGCHLD is blocked, some executables (for example CMake) do not exit properly when executed using `SDL_CreateProcess` from any SDL thread (not main thread). `SDL_CreateProcessWithProperties` docs say that `SIGCHILD` should not be ignored or handled, therefore blocking it during thread creation is a likely reason for the bug. Should fix #15210.
