2e5a20612c libc: unistd: lib_getrlimit: return a value for RLIMIT_NOFILE request.
In the Nim language "selectors"(I/O multiplexing) module, the maximum
number of file descriptors is obtained with getrlimit() as follows.

        var fdLim: RLimit
        var res = int(getrlimit(RLIMIT_NOFILE, fdLim))
        if res >= 0:
          res = int(fdLim.rlim_cur) - 1

To be able to use the same implementation as other POSIX-based OS,
getrlimit() should return a value.
(For now, let it return 128.)

4c8d244fae 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.
