system: introduce BR2_SYSTEM_DEFAULT_PATH option

The configuration option BR2_SYSTEM_DEFAULT_PATH allows the user to override the default path, which can be used by /etc/profile and some system daemons. It defaults to the value previously hard-coded in /etc/profile. This default should be suitable for most users. Signed-off-by: Markus Mayer <[email protected]> Reviewed-by: "Yann E.
