[Newcomer][PATCH] graph.c: change graph_line->width type to int to remove sign-compare warning

[Octavio Carneiro <ocarneiro1@gmail.com>]

A comparison between graph_line->width (of type size_t) and git_graph->width (of type int) causes -Wsign-compare to complain.

Looking at the git_graph struct definition, its size variables are int-typed.

Therefore, I changed the type of graph_line->width to also be a int, thus removing the warning trigger.
