libc/sys/rtems/crt0.c: Add <sys/lock.h> symbols required to link autoconf probes 

The dummy crt0.c provided by the RTEMS target provides stubs of
symbols which would normally be provided by RTEMS. This patch adds
stubs for posix_memalign() as well as the synchronization methods
prototyped in <sys/lock.h>.
