bootc: Update revdep test for current bootc main

bootc now depends only on the cfsctl crate, which re-exports the
other composefs-rs crates. Simplify the patch to only override
cfsctl. Also pass all four required arguments through to bootc's
test-composefs target (bootloader, filesystem, boot_type, seal_state),
defaulting to the sealed UKI configuration that build-sealed produces.
