APP CRASH: drrun -s or -m or -h timeout affects the exit status in case of abnormal process termination

With DynamoRIO-AArch64-Linux-9.0.1 i see
```
$ ./a.out
Aborted (core dumped)
$ drrun ./a.out
Aborted (core dumped)
$ drrun -s 99 ./a.out
$ echo $?
0
```
for
```
#include
int main()
{
abort();
}
```

i expect the timeout to not affect the exit status (unless the timeout is actually reached).

(for me this means that i cannot run toolchain tests under dynamorio as the timeout flag breaks the test exit status, and without timeout some tests hang due to dynamorio bugs).
