Update etcetera to 0.11; no longer depend on home; MSRV 1.87

Release 0.11 of `etcetera` requires MSRV 1.87, in which
`std::env::home_dir` is no longer deprecated,
https://github.com/rust-lang/rust/pull/137327.

Update to that MSRV and to `etcetera`, and drop the dependency on the
`home` crate just as `etcetera` 0.11 did.
