LOADER: portability fix

[Hans Leidekker]

The code in loader/pthread.c is protected by #ifdef HAVE_PTHREAD_H,
as is the code code in the header include/wine/pthread.h. This patch
does the same for loader/kthread.c since it uses the same functions
and structures. With this patch the code in loader/ compiles without
errors on MinGW.

Changelog:
  Protect use of pthread functions with #ifdef HAVE_PTHREAD_H.
