[PATCH 2/6] libsepol/cil: Store CIL filename in parse tree and AST

[James Carter <jwcart2@xxxxxxxxxxxxx>]

Use some of the functionality recently added to support high-level
language line marking to track the CIL filename.

The goal is to eventually remove the path field from the tree node
struct and offset the addtion of the hll_line field.
