/dev/fd/0 may not be stat()-able on some systems after dropping
permissions from root to a regular user.  So just check for
"/dev/fd" which seems to work on RHEL 2.6.18 kernels.  This also
allow us to be used independently of Unicorn in case somebody
ever feels the compelling need to /close/ stdin.
