sshfs_mount: rename to sshfs_forward_mount

In preparation for adding reverse mounting capabilities we'll rename
all existing functions to be known as "forward mounting" where:

- reverse: mounting guest directory onto the host
- forward: mounting host direcotry into the guest

Forward mounting is how vagrant-sshfs acts today and is the most
common use case.
