When building cargo-c with DEBUG mode, QA checks fail due to
absolute paths from the build environment (TMPDIR) being embedded into
the debug symbols/binaries. This causes issues such as:

  ERROR: do_package_qa: File /usr/bin/.debug/cargo-capi contains reference to TMPDIR [buildpaths]
  ERROR: do_package_qa: File /usr/bin/.debug/cargo-cinstall contains reference to TMPDIR [buildpaths]
  ERROR: do_package_qa: File /usr/bin/.debug/cargo-cbuild contains reference to TMPDIR [buildpaths]
  ERROR: do_package_qa: File /usr/bin/.debug/cargo-ctest contains reference to TMPDIR [buildpaths]

To fix this, pass an additional -ffile-prefix-map option to DEBUG_PREFIX_MAP to
ensure that paths under `${CARGO_HOME}` are remapped to `${TARGET_DBGSRC_DIR}`.
This ensures debug info is reproducible and does not leak host-specific paths.
