Several small improvements
 
Summary:

This has several small improvements.

benchmark.sh
* add BYTES_PER_SYNC as an env variable
* use --prepopulate_block_cache when O_DIRECT is used
* use --undefok to list options that don't work for all 7.x releases
* print "failure" in report.tsv when a benchmark fails
* parse the slightly different throughput line used by db_bench for multireadrandom
* remove the trailing comma for BlobDB size before printing it in report.tsv
* use the last line of the output from /bin/time as there can be more than one line
  when db_bench has a non-zero exit
* fix more bash lint warnings
* add ",stats" to the --benchmark=... lines to get stats at the end of each benchmark

benchmark_compare.sh
* run revrange immediately after fillseq to let compaction debt get removed
* add --multiread_batched when --benchmarks=multireadrandom is used
* use --benchmarks=overwriteandwait when supported to get a more accurate measure of write-amp

Test Plan:
Run it for leveled, universal and BlobDB
