reftable: consistently refer to `reftable_write_options` as `opts`

Throughout the reftable library the `reftable_write_options` are
sometimes referred to as `cfg` and sometimes as `opts`. Unify these to
consistently use `opts` to avoid confusion.

While at it, touch up the coding style a bit by removing unneeded braces
around one-line statements and newlines between variable declarations.
