build: add profile for small binary sizes

This commit adds the "small" profile to Cargo.toml, optimized for small binary sizes. To use it, simply run: $ cargo build --profile=small Using this profile, the holod binary size shrinks to 12M on my machine, down from 21M with the default "release" profile.
