Denys Vlasenko 41ef41b3e0 hush: fix nested redirects colliding with script fds 
This necessitates switch from libc FILE api to a simple
homegrown replacement.
The change which fixes the bug here is the deleting of

	restore_redirected_FILEs();

line. It was prematurely moving (restoring) script fd#3.
The fix is: we don't even _want_ to restore scrit fds,
we are perfectly fine with them being moved.
The only reason we tried to restore them is that FILE api
did not allow moving of FILE->fd.
