kbuild, rust: use -fremap-path-prefix to make paths relative
Remap source path prefixes in all output, including compiler
diagnostics, debug information, macro expansions, etc.
This removes a few absolute paths from the binary and also makes it
possible to use core::panic::Location properly.
Equivalent to the same configuration done for C sources in
commit 1d3730f0012f ("kbuild: support -fmacro-prefix-map for external
modules") and commit a73619a845d5 ("kbuild: use -fmacro-prefix-map to
make __FILE__ a relative path").
