include/sys/resource.h: Add four resource limits of Linux and BSD.
RLIMIT_RSS, RLIMIT_NPROC, RLIMIT_LOCKS and RLIMIT_SIGPENDING were
missing. Linux and the BSDs have them, and programs use them without a
check (the ulimit command of shells, for example). Such programs did not
compile.
Add them at the free values 9, 11, 12 and 13. NuttX does not enforce
them: getrlimit() reports RLIM_INFINITY, as for the other limits that
NuttX does not enforce, and setrlimit() fails with EINVAL, as for those.
RLIM_NLIMITS does not change.
