[Buildroot] [PATCH v2] package: dropbear: make PATH configurable

[Markus Mayer <mmayer@broadcom.com>]

Make the default PATH dropbear is using configurable.

If not specified, it will continue to default to dropbear's
DEFAULT_PATH.

Signed-off-by: Markus Mayer <mmayer@broadcom.com>

Changes since v1:
- Made regex safer
  + allow multiple spaces after #define
  + make sure there are spaces or tabs after DEFAULT_PATH
