The path configuration macros are often supplied to get_relocated_path(), and the function had some logics to remove the prefixes. With this change, the prefixes are removed from those macros and get_relocated_path() is also simplified. This also fixes --firmwarepath configuration option. The old implementation naively added the prefix to the given option although it is a list of paths. Now an absolute path in --firmwarepath will be used as-is. A relative path in --firmwarepath will be relocated with get_relocated_path().
