Fix installing dependencies on Fedora and remove usage of distro.linux_distribution()

<!-- Please describe your changes on the following line: -->
`./mach bootstrap` wasn't installing dependencies on Fedora, so I fixed that.
And I removed the usage of `distro.linux_distribution()`, because it's a deprecated function.
This is my first attempt at contributing to Servo, so I hope I did everything right :D
