app-misc/anki: ensure build runner and configure are built for CBUILD

These changes have not yet been tested in an actual cross environment
but since the build system respects Cargo environment variables, this
should hopefully work.

Bump the revision of this ebuild because the build now honors LDFLAGS
among other RUSTFLAGS set in cargo_env in the cargo eclass.

-Provide the binary ourselves to prevent network access.
+Fix the output path for Rust binaries in the Ninja file to match
+Cargo's target directory when CARGO_BUILD_TARGET is set.  This prevents
+file-not-found errors for some build steps.

+Provide the cargo-nextest binary ourselves to prevent network access.
 Set test runner options in the ebuild.
