executor: don't use WUNTRACED in wait
...
WUNTRACED wait returns when child has stopped.
That's not what we want to wait for.
If it's stopped we need to timeout wait and kill
the stopped child.

use fork server in executor
...
This avoids exec per test.
Also allows to pre-map shared memory regions.
And will allow to pre-map coverage regions, etc.
Seems to work already, but probably there are still some bugs.

open /proc/cover only once in executor
...
First, it is just not necessary to open it multiple times.
But more importantly a program can close fds that it previosuly used:
r0 = open(...)
close(r0)
close(r0)
and this can close cover fds created in threaded mode.
