Various examples fixes (raylib-rs#115)

* Remove [[example]] entries of raylib/Cargo.toml

Those entries actually point nowhere and makes cargo build --examples fail confusingly.
As they are actually replaced with what we have in samples, we can remove them.

* Remove examples scrapping

As we don't have a raylib/examples directory, this feature doesn't do anything anymore.

* Bump rand dependency in samples.

3d_camera_first_person uses gen_range expecting a range, which is only the case for rand 0.8.

* Remove excessive parents in shader multisample example

Fixes a cargo check warning.
