Cleanup, LineArt: Fix MSVC compiler warnings.

Currently 3 of the printf lines use the format specifier "%lu" for data
of type size_t instead of "%zu". While this works, this creates compiler
warnings.

This diff fixes those warnings by using the correct format specifier.
Tested using MSVC, but should be correct on any compliant compiler.
