[Buildroot] [PATCH v3 4/4] dropbear: use BR2_SYSTEM_DEFAULT_PATH as default PATH

[Markus Mayer <mmayer@broadcom.com>]

We use the configuration option $(BR2_SYSTEM_DEFAULT_PATH) to set the
default PATH in dropbear sessions.

$(BR2_SYSTEM_DEFAULT_PATH) is a Kconfig string. So it is already
quoted, which is exactly what we want.
