Deactivating cargo tarpaulin

[Razican]

cargo tarpaulin is failing on every commit due to xd009642/tarpaulin#517, which is also reported in cargo in rust-lang/cargo#9220, and should be fixed when rust-lang/cargo#9229 lands.

For the time being, we can deactivate coverage checks, which should make builds start to pass again.
