gpsd: remove patch to handle ncurses5-config custom location

Now that ncurses has been bumped to 5.9, it installs .pc files for
pkg-config, which allows gpsd to find it properly without the need to
specify a custom location for ncurses5-config.

Since gpsd now uses pkg-config to find the ncurses library, we also
add host-pkg-config in the dependencies.

-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
-ncurses5-config. We add an option that allows to specify a custom path
-to the ncurses5-config script.
