Test shell script doesn't work in macOS

[douglascamata]

I tried to run the test shell script in macOS and it returns this:

⋊> ~/c/r/fd on master ⨯ sh tests/test.sh                                                                                         14:25:13
mktemp: illegal option -- -
usage: mktemp [-d] [-q] [-t prefix] [-u] template ...
       mktemp [-d] [-q] [-u] -t prefix

I believe this might be fixed by replacing mktemp --directory by mktemp -d. Unfortunately, I don't have a macOS system to test...

I've just updated the test.sh script. I'd be great if somebody could test this.

@sharkdp I'll test it.

Still failing:

This should hopefully be fixed now, tested on El Capitan.
