PR 68980
    libgo/testsuite: portable ps usage in gotest
    
    gotest is using "ps" to list descendant sleep
    processes in its timeout handling, grepping
    the command name.
    
    We are currently using the "cmd" ps output
    formatter, which is non-portable. We should
    use "comm" which is part of the POSIX
    standard, and outputs only the command name
    and not the arguments.
