internally, define time64 rusage syscalls on x32 as the existing ones
this is analogous to commit 40aa18d55ab763e69ad16d0cf1cebea708ffde47. so far, there are not any actual time64 versions of the rusage syscalls (getrusage and wait4) and might never be. however, the existing x32 ones behave the way time64 versions would if they existed: using 64-bit slots in place of all longs. presently, wait4 and getrusage are broken on x32, storing the timevals correctly but messing up everything else due to the long/kernel-long mismatch. this would be a huge buffer overflow if not for the 16 reserved slots we left long ago, which suffice to prevent 14 double-sized longs from overflowing into unrelated memory. this commit will make it possible to fix them.
