[hurd,commited 1/3] htl: Fix includes for lockfile

[Samuel Thibault]

These only need exactly to use __libc_ptf_call.

* sysdeps/htl/flockfile.c: Include <libc-lockP.h> instead of
<libc-lock.h>
* sysdeps/htl/ftrylockfile.c: Include <libc-lockP.h> instead of
<errno.h>, <pthread.h>, <stdio-lock.h>
* sysdeps/htl/funlockfile.c: Include <libc-lockP.h> instead of
<pthread.h> and <stdio-lock.h>
