Tim Heckman cb5d1da986 Add support for home directory expansion for -c/--config flag
This change introduces the ability to use the tilde (`~`) character in your
`-c/--config` flag value to expand your home directory. If invoking this via the
command line with `--config ~/.golangci-lint.yaml`, the user's shell expands the
`~` to the home directory. However, if something is invoking the program for
you (like an editor) it may not do the expansion.

Fixes #289

# 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.
