environment: improve the TTY check (#1785)

Browse source 
Bug report from @qosmio:
https://github.com/sorin-ionescu/prezto/pull/1771#issuecomment-575596417

I'm unable to reproduce it and @qosmio hasn't yet confirmed or
disconfirmed whether this fix works. It's a good idea to change
the code this way in either case.

(As I mentioned in #1771, this `stty -ixon` call may have been added
by mistake. It doesn't do what the comment suggest and is at least as
likely to be harming users as helping them.)
