selftests/bpf: Add --no-error-summary to skip end-of-run error log dump

By default test_progs re-prints the aggregated error logs of all failed
tests at the end of the run (when not in verbose mode), starting with
"All error logs:".

With bpf-gcc the current failures and a couple runaway 1M fails cause a
huge print overhead/delay at the end.

Add a subtractive --no-error-summary flag, gated on a new
env.error_summary field which defaults to true, so the default behavior
is unchanged. Passing --no-error-summary suppresses the final
"All error logs:" dump.

Only the human readable output is elided. dump_test_log() also emits the
per-test and per-subtest entries of the --json-summary "results" array,
so it keeps being called (via a new @quiet argument) and the JSON report
is bit for bit what it was before.
