Disable slasher default features

[SamWilsn]

Issue Addressed

Because slasher had lmdb as a default feature, it was impossible to have a pure mdbx build of lighthouse.

Proposed Changes

This commit sets default-features = false for slasher so lighthouse can actually choose one or the other.

The use case here is that you want to build Lighthouse with cargo build --release --no-default-features and have that exclude LMDB, right? You don't mind building with the extra --no-default-features flag?

No particular use case in mind. Just seemed odd that the lighthouse crate had a slasher-lmdb feature that, when disabled, didn't actually disable the lmdb feature in the slasher crate.

You don't mind building with the extra --no-default-features flag?

This is part of my "packaging Lighthouse for Gentoo" saga. In Gentoo, the default for Rust crates is to compile with --no-default-features and have USE flags that map to the features of the crate.
