Run clippy on MSRV

Since not all suggested clippy lints by stable clippy are supported on
the MSRV of Alacritty, this commit moves the clippy checks to the MSRV.

Unfortunately this will mean that our lints might be significantly
behind, however it ensures our CI never blocks any code that should be
valid.

Developers themselves of course can still run the latest clippy to
follow the up to date recommendations.
