`#[cfg(mobile)] fn install_inner` returned `Ok(())` without doing anything.
`check` already fails with `UnsupportedOs` there unless a Rust caller sets a
custom target, in which case a download was followed by a successful
"install" that did nothing. It now returns `Error::UnsupportedOs`, the error
`check` uses.
Verified with clippy for aarch64-linux-android (the iOS build needs the Swift
package, which does not build here).
