profile: Fix rusage reporting

2023-12-19T16:05:36+00:00

getrusage already gives accumulated values, so add them to the tdb
record after smbprofile_stats_accumulate. Maybe we should not zero out
our internal copy after writing the tdb, this would save a call to
smbprofile_stats_accumulate() once a second.
