[OE-core] [PATCH V3 07/11] bitbake.conf: Enable -fdebug-prefix-map for nativesdk

[Robert Yang]

Files like lib/.debug/libgcc_s.so.1 from nativesdk-libgcc-dbg contains
buildpath without -fdebug-prefix-map, the root cause is object files (.o)
contain buildpath, and then ccache can't use them correctly.
