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.
