gpsd: fix build issues

The first patch gpsd-01-sconstruct-python-2.5-compat.patch is aimed at
fixing Python 2.5 compatibility issues such as:

 http://autobuild.buildroot.org/results/844a7f8698567688eba094f64dd2bf5157efd994/build-end.log

The second patch gpsd-02-sconstruct-ncurses-config-path.patch
implements a proper mechanism to specify the path to
ncurse5-config. It obsoletes the previous
gpsd-fix-acs_map-compile-errors patch, and solves build problems such
as:

+Remove all the with ... as foo constructs
+
+Those constructs have been introduced in Python 2.6, and some of our
+autobuilders still use Python 2.5, so replace them with constructs
+that are compatible with Python 2.5.

+Add option to specify the path to ncurses5-config

+By default, gpsd's SConstruct looks in the PATH to find
+ncurses5-config, which means that it finds our HOST_DIR
