oeqa/buildperf: don't archive stdout/stderr of commands

Stop capturing output of the shell commands into <test>/commands.log.
Redirecting output into a file prevented the unittest framework from
capturing it, causing useless errors (with empty output) like:
oeqa.utils.CommandError: Command '['bitbake', 'core-image-sato']'
returned non-zero exit status 1 with output:

In general, the console output of commands is only interesting when
something fails. Also, dropping the commands.log file is a huge saving
in disk space, and thus, repository size when results are archived in
Git.
