tools: moveconfig: fix needless move for config with default 1

When moving an integer type option with default value 1, the tool
moves configs with the same value as the default (, and then removed
by the later savedefconfig).  This is a needless operation.

The KconfigParser.parse_one_config() should compare the config after
the "=y -> =1" fixup.
