  Cache per-CPU agg map IDs

The dt_bpf_map_lookup_fd(dtp->dt_aggmap_fd, &cpu) call that is used to
snap or truncate aggregations takes a few milliseconds, which seems all
right.  For large systems (e.g., 100 CPUs) and many truncations (e.g.,
tst.trunc.d, etc.), however, a trunc() might end up costing a minute on
the consumer side, which is unreasonable and causes such tests to time
out.  The run time is due almost exclusively to looking up the per-CPU
agg map ID.

Cache the per-CPU agg map IDs.

  test: Convert tick-* probes to ioctl:entry for tst.trunc[quant].d

Historically, many tests have used tick-* probes to get multiple
probe firings, but those probes can be unreliable, depending on
how a kernel is configured.  Tests that required very many probe
firings have been converted to ioctl:entry.  Tests that required
very few have been left alone.

Convert more of these tests.  They normally pass, but with erratic
execution time and sometimes time out.

  Log Message:
  -----------
  test: Mimic dtrace arithmetic more closely for avg/stddev

The multicpus test checks that data from multiple CPUs is aggregated
properly.  Operations like avg() and stddev() require division.
DTrace uses integer division, while awk does not.

Change the awk check to truncate intermediate results after division.

In practice, intermediate results are typically integer values anyhow.
So the test has generally passed.  Non-integer values could arise if,
for example, CPUs are not numbered consecutively.  More typically,
there may be a problem that the profile probe is not firing on every
expected CPU.  So a test failure probably was a sign of a problem,
but that's a different problem, one beyond the scope of this test.
