support `-` as an argument to `rails runner`
in Rails 4.0, you could use `/dev/stdin` on both Linux and Mac, but with
the switch to Kernel.load in Rails 4.1, this broke on Linux (you get
a LoadError). Instead, explicitly detect `-` as meaning stdin, then
read from stdin explicitly, instead of performing file gymnastics. This
should now work on any platform uniformly.
Passing a script via stdin is useful when you're sshing to a server,
and the script you want to run is stored locally. You could theoretically
pass the entire script on the command line, but in reality you'll run
into problems with the command being too long.
