define RLIMIT_RTTIME, bump RLIMIT_NLIMITS
This macro exists since Linux 2.6.25 [1] and is defined in glibc
since 2.14 [2] for sparc and most supported architectures.
RLIMIT_RTTIME has been added later for mips [3] and alpha [4].
For example, RLIMIT_RTTIME is needed to build qemu 7.0.0 with
Linux user-land emulation support [5].
