[libgpiod][PATCH v4 20/20] bindings: python: make vals in gpiod_Line_set_value consistent with other functions

[Kent Gibson <warthog618@gmail.com>]

Change the vals in gpiod_Line_set_value from a tuple of tuples to just a
tuple.  This brings it into line with other vals in the module such as
gpiod_Line_set_config and gpiod_Line_set_direction_output.

The previous usage made the vals equivalent to an args (a tuple of
arguments equivalent to argc,argv in C), as per gpiod_Line_set_flags.

Renaming vals to args in gpiod_Line_set_value was not an option as there
is already an args parameter.
