test(build-std): resolve too less deps

This failed because since 125e873 [`std_resolve`][1] only includes `sysroot` as primary package. When any custom Cargo feature is provied through `-Zbuild-std-feature`, the default feature set `panic-unwind` wouldn't be gone, so no `panic_unwind` crate presents in `std_resolve`. When then calling [`std_resolve.query`][2] with the default set of crates from [`std_crates`][3], which automatically includes `panic_unwind` when `std` presents, it'll result in spec not found because `panic_unwind` was not in `std_resolve` anyway.
