Bug #11613: test_aspawn_too_long_path creates too many processes

----------------------------------------
At least on FreeBSD, spawn("echo|echo|echo|echo|echo|echo|echo| ...20000 times") success and create 20000 zombie processes.
To prevent this you can add rlimit_nproc: 1 because it tests sh itself, don't test spawned echos.
