ash: do not abort interactive mode on >&9999 redirect

With very large fd#, the error code path is different
from one for closed but small fd#.

Make it not abort if we are interactive:

$ echo text >&99    # this wasn't buggy
ash: dup2(9,1): Bad file descriptor
$ echo text >&9999  # this was
ash: fcntl(1,F_DUPFD,10000): Invalid argument
