This reverts commit 07d8a676aa962ecc5ec264ec33b0074adf2a8733.
This commit incorrectly assumed that ptest ran tests in parallel, which
is not true. Doing so interleaves the test output in the log file, which
the OE selftest parser cannot handle and thus breaks the test cases.

The write end of the pipe has to be closed by ptest-runner to make sure
that it will get EOF when the child process is done with it. This means
that a new pipe needs to be opened for each child so that the write ends
can be passed to it.
Fixes the problem where tests would be reported with no output when
ptest-runner was told to run multiple tests because they were passed
invalid stdin/stderr pipes.

To: yocto; +Cc: Joshua Watt
Changes the way that tests time out to be the total elapsed time for the
test, not just the time between receiving output from the test. This
matches the implementation before 8259375 ("runner: Remove threads and
mutexes").
Also update the timeout test case to test for this correctly.
