vfs: simplify the `abstractvfs.rename()` implementation

PyCharm was yapping about `util.rename()` not returning anything, because it is
typed to return `None`, but the value was captured and returned after calling
`_avoidambig()`.  Instead, drop all of that, unconditionally rename, and then
call `_avoidambig()` if appropriate.

While we're here, convert the ersatz ternary operator into a modern one to help
pytype.  When a variable is initialized the old way, pytype tends to assign the
type of the LHS of the `and`.  In this case, that's a bool, and it will get
confused that bool doesn't have a `stat` attribute once this method gets more
type annotations.  (Currently it thinks the `checkambig` arg is `Any`, so it
doesn't care.)
