Ian Rogers 8b93f8933d perf test shell lock_contention: Extra debug diagnostics ...

In test_record_concurrent, as stderr is sent to /dev/null, error
messages are hidden. Change this to gather the error messages and dump
them on failure.

Some minor sh->bash changes to add some more diagnostics in
trap_cleanup.
