build.config: drop setting of BUILDTOOLS_PREBUILT_BIN

to use the default value specified in build.config.common.
Otherwise the tools in build-tools used will not be found,
like the build error reported here[1]:
    build/build.sh: line 983: soong_zip: command not found

[1]: https://ci.android.com/builds/submitted/9574600/kernel/latest/view/logs/build_error.log

Test: build the x15 4.14 kernel successfully
