Subject: [PATCH] Configure new `check-cfg` lint that `coverage` is an allowed
 option (#722)

The lastest Rust nightly [adds checking for cfgs] and their possible
values.  This requires us to define via `build.rs` that `coverage` is a
valid `cfg`, and that it is a "boolean" without any allowed values.
