linux: handle read-only dts files
Some fine version control systems make all files read-only. The custom DTS file may therefore be read-only, and that permission is preserved when copying into the Linux build directory. A subsequent rebuild tries to 'cp' again, which fails with a "Permission denied" error unless the -f option is used.
