Fixing thread start_routine signatures in tests

pthread_create function requires that start_routine has void*(void*)
signature. However many tests defined this function as void*(void). When
compiling such test to native code such pointer was implicitly casted.
In case of Emscripten such casts are won't work and resulted in exception
thrown at JavaScript side.

This patch adjust tests start_routine to have proper signature.
