[x265] [PATCH] threading.h: fix WaitForSingleObject return type

[Johannes Kauffmann]

WaitForSingleObject returns a DWORD, which is unsigned. This fixes the
following warning for every threading.h include:

  threading.h:285:41: warning: comparison of integer expressions of different signedness: ‘int32_t’ {aka ‘int’} and ‘DWORD’ {aka ‘long unsigned int’} [-Wsign-compare]
    285 |         return rt != WAIT_TIMEOUT && rt != WAIT_FAILED;
