py3: use class X: instead of class X(object):

The inheritance from object is implied in Python 3. So this should
be equivalent.

This change was generated via an automated search and replace. So there
may have been some accidental changes.

# By default, use our own standalone_fuzz_target_runner.
# This runner does no fuzzing, but simply executes the inputs
# provided via parameters.
# Run e.g. "make all LIB_FUZZING_ENGINE=/path/to/libFuzzer.a"
# to link the fuzzer(s) against a real fuzzing engine.
#
# OSS-Fuzz will define its own value for LIB_FUZZING_ENGINE.
LIB_FUZZING_ENGINE ?= standalone_fuzz_target_runner.o

# Default to Python 3.
#
# Windows ships Python 3 as `python.exe`, which may not be on PATH.  py.exe is.
