refs: rename `refs_create_symref()` to `refs_update_symref()`

The `refs_create_symref()` function is used to update/create a symref. But it doesn't check the old target of the symref, if existing. It force updates the symref. In this regard, the name `refs_create_symref()` is a bit misleading. So let's rename it to `refs_update_symref()`. This is akin to how 'git-update-ref(1)' also allows us to create apart from update. While we're here, rename the arguments in the function to clarify what they actually signify and reduce confusion.
