[PATCH] getrlimit: prefer __NR_ugetrlimit over __NR_getrlimit

Most architectures in the linux kernel define both __NR_ugetrlimit
and __NR_getrlimit syscalls.  The __NR_ugetrlimit syscall provides a
SuS complient getrlimit() implementation and __NR_getrlimit() an
uncompliant implementation with 2Gi limits.

The patch prefers __NR_ugetrlimit when both syscalls are available and
is required for architectures (e.g. ARM-EABI) where __NR_getrlimit
support was removed.
