Add more stubs to RTEMS dummy crt0

[Joel Sherrill]

This patch adds more stubs to the RTEMS crt0.c so
autoconf probes for gfortran and Go are happy
with RTEMS. The crt0 stub satisfies symbols which will
really only be available when an actual RTEMS image
is linked against.

OK to apply?

     * libc/sys/rtems/crt0.c: Add stubs for access(), ftruncate(),
     _getpid_r(), geteuid(), getgid, _getgid_r, getpid(), getppid(),
     and _getpid_r().
