This should reallly fix the time command not working on travis..

Turns out time is a shell keyword and a command, the command is not
installed on Ubuntu by default, therefor I'm installing it first.
You can also simply run the tests without time by launching them using
$ make test TIME=
I sort of demand the real time as it gives more useful information.

Also I'm on a train..
