slog: improve benchmark handling

Make some improvements to how benchmarks are run, motivated
by the latest benchstat
(https://pkg.go.dev/golang.org/x/perf/cmd/benchstat).

- Run each benchmark 10 times, the minimum recommended in the
  benchstat package doc.

- Use the -ignore flag to benchstat to remove the need to edit
  the "pkg" line in benchmark output.

- Create a Makefile to put all benchmark-running code in one place.
  - Remove all run_benchmarks.sh scripts.
  - Use the same name for each subdirectory's output file to enable
    a single Makefile rule.
