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.
