Two independent gaps in misc.c/job.c, both silently zeroing every real
job's resource-usage data:
- update_host_runusage() matched worker rusage report resnames
"cputime"/"mem", but the real worker's collector
(collect_job_rusages(), xcecd_cgroups.c) sends "cpu_time_sec"/
"memory_rss" -- the two never matched, so cpu_time/mem_usage stayed
at their calloc()'d zero for every non-simulated job. Aligned both
sides, including xce_test's own simulated-worker fixture.
- update_job_rusages() had a standing FIXME: xce_job_runusage_t's
job-level max_mem/avg_mem/used_mem/cpu_time were never derived from
the per-host host_runusage[] entries. Added aggregate_job_runusage()
(sum/max/avg across hosts) and wired it in right after the per-host
update.
Added test_host_runusage.c (standalone unit test, mirrors
resval_typeresolve_unit_test's isolation pattern) plus the
controller_unit_test stub aggregate_job_runusage() needs since that
target excludes the real misc.c.
