rust: io: fix broken intra-doc link to missing `flags` module

There is no `mod flags` in this case, unlike others. Instead, they are
associated constants for the `Flags` type.

Thus reword the sentence to fix the broken intra-doc link, providing
an example of constant and linking to it to clarify which ones we are
referring to.
