Remove bsd/include/pthread_np.h

The header file "bsd/include/pthread_np.h" is not needed, and the only
place that includes it, didn't have to.

The definitions in that file only introduce a chance of collision with
similar definitions in api/pthread.h (e.g., in an upcoming patch for adding
pthread_attr_setaffinity_np), so better not have them at all.

Httpserver: add to "make clean"

Add httpserver cleanup to "make clean" (previously this was in mgmt/'s
Makefile, but now we moved it out of mgmt and need to fix "make clean" too).
