provider/lang: expand() g:foo_host_prog (#9312)

Browse Source 
Before this commit, if user does this:
    let g:node_host_prog = '~/.nvm/versions/node/v11.3.0/bin/neovim-node-host'
the "~/" is not expanded to user's home directory.

`:help g:ruby_host_prog` suggests a path with "~/" so technically we
already claimed to support this.

Expand() can also be used to expand variables and environment
expand() can also be used to expand variables and environment
variables that are only known in a shell. But this can be
slow, because a shell may be used to do the expansion. See
|expr-env-expand|.
