Unnecessary wasm binaries

[larry0x]

Currently when we run cargo make rust-optimizer, the following two wasm binaries are generated:

mars_rewards_collector_base-aarch64.wasm
mars_zapper_base-aarch64.wasm

However these two are not actually used (not to be deployed on a chain).

We can avoid compiling them by removing the following line from their Cargo.tomls:

[lib]
crate-type = ["cdylib", "rlib"] # remove!!
