Fixes gps/*.py to use new-style classes.

Although this isn't strictly a Python 3 requirement, using the
new-style class definition syntax improves consistency between Python
2 and Python 3.  Old-style classes have been deprecated since Python
2.2, but many such definitions linger on.  Python 3 eliminates
old-style classes, but instead of complaining about old-style
definitions, it simply unconditionally and silently makes all classes
new-style.  The only incompatible differences are quite subtle and
rarely matter in practice, but things are more consistent across
versions if the new-style definitions are used.

Also, the preferred method for subclasses to invoke parent init
methods is via the super() construct, which is only available with
new-style classes.  Using super() is especially useful with multiple
inheritance, which it handles automatically (provided that the init
methods have compatible signatures).

TESTED:
Ran "scons build-all check valgrind-audit", as well as gegps, gpscat,
gpsprof, xgps, and xgpsspeed, with all six supported Python versions
(except 2.6 for xgps*).
