jit: avoid calloc() poisoning on musl [PR106102]
On musl <pthread.h> uses calloc() (via <sched.h>). jit/ includes
it directly and exposes use of poisoned calloc():
/build/build/./prev-gcc/xg++ ... ../../gcc-13-20220626/gcc/jit/jit-playback.cc
make[3]: *** [Makefile:1143: jit/libgccjit.o] Error 1
make[3]: *** Waiting for unfinished jobs....
In file included from /<<NIX>>/musl-1.2.3-dev/include/pthread.h:30,
from ../../gcc-13-20220626/gcc/jit/jit-playback.cc:44:
/<<NIX>>/musl-1.2.3-dev/include/sched.h:84:7: error: attempt to use poisoned "calloc"

124 | #define CPU_ALLOC(n) ((cpu_set_t *)calloc(1,CPU_ALLOC_SIZE(n)))
| ^
The change moves <pthread.h> inclusion to "system.h" under new
INCLUDE_PTHREAD_H guard and uses this mechanism in libgccjit.
