devel/py-llfuse: fix build with clang 15

During an exp-run for llvm 15 (see bug 265425), it turned out that
devel/py-llfuse failed to build with clang 15:

  src/llfuse.c:41839:21: error: incompatible pointer to integer conversion assigning to 'uintptr_t' (aka 'unsigned int') from 'pthread_t' (aka 'struct pthread *') [-Wint-conversion]
          __pyx_v_tid = __pyx_t_7;
                      ^ ~~~~~~~~~

  1 warning and 1 error generated.

The conversion from pthread_t to uintptr_t needs an explicit cast.
