sched/getpid: replace syscall getpid/tid/ppid() to kernel version
...
NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.

libc/sched: Map the nice value more correctly
...
from https://pubs.opengroup.org/onlinepubs/007904875/functions/setpriority.html :
1.The nice value shall in the range [-{NZERO},{NZERO} -1]
2.Lower nice value shall cause more favorable scheduling

sched: Don't include nuttx/sched.h inside sched.h
...
But let nuttx/sched.h include sched.h instead to
avoid expose nuttx kernel API to userspace.
