localkube should not use /usr/lib/systemd/system for service unit files

[easeway]

Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG REPORT

Please provide the following details:

Environment:

Minikube version : v0.22.3 (commit id: 3358402)

• OS : Ubuntu 17.04
• VM Driver : none
• ISO version :
• Install tools:
• Others:

What happened:
E1020 10:45:30.305707 13466 start.go:150] Error starting host: Error starting stopped host: mkdir /usr/lib/systemd/system/: permission denied.

What you expected to happen:
On ubuntu, service unit files are under /lib/systemd/system.
The right place to create systemd unit files should be /etc/systems/system which is unified across all systemd based distributions.

How to reproduce it (as minimally and precisely as possible):
minikube start --vm-driver=none

Output of minikube logs (if applicable):

Anything else do we need to know:

./pkg/minikube/constants/constants.go:140:	LocalkubeServicePath = "/usr/lib/systemd/system/localkube.service"
./pkg/drivers/none/none.go:153:	if err := os.MkdirAll("/usr/lib/systemd/system/", os.FileMode(0755)); err != nil {

The constant LocalkubeServicePath should be /etc/systemd/system which is consistent across different distributions.
In none.go, the constants should be used instead of a string literal. Actually, mkdir is not necessary here.

Is there a temp fix aside from building from source?
