tests/noshebang: Sleep before executing a file we just wrote to

Browse source 
When you try to execute a file directly after you've written to it,
you might, on some systems, get a "text file busy" error.

So we unfortunately have to sleep to avoid it.

See #8021 for where this was added,
537b3f6cb1 for the same problem.
