[PATCH 2/2] Revert "kbuild, rust: use -fremap-path-prefix to make paths relative"

[Thomas Weißschuh]

This reverts commit dbdffaf50ff9cee3259a7cef8a7bd9e0f0ba9f13.

--remap-path-prefix breaks the ability of debuggers to find the source
file corresponding to object files. As there is no simple or uniform
way to specify the source directory explicitly, this breaks developers
workflows.

Revert the unconditional usage of --remap-path-prefix, equivalent to the
same change for -ffile-prefix-map in KBUILD_CPPFLAGS.
