Use path/filepath over hardcoded path separators.

What
===
Change tests to use `path/filepath` instead of `fmt` and hardcoded `/`
path separators.

Why
===
Joining paths with `/` causes the tests to fail when run on windows because it's file path separator is `\`. Using `path/filepath` allows the code to join paths together using the system path separator without the code needing to know what the separator is.

go-homedir

This is a Go library for detecting the user's home directory without the use of cgo, so the library can be used in cross-compilation environments.

Usage is incredibly simple, just call homedir.Dir() to get the home directory for a user, and homedir.Expand() to expand the ~ in a path to the home directory.

Why not just use os/user? The built-in os/user package requires cgo on Darwin systems. This means that any Go code that uses that package cannot cross compile. But 99% of the time the use for os/user is just to retrieve the home directory, which we can do for the current user without cgo. This library does that, enabling cross-compilation.
