[PATCH V2] timezone: Fix compare_file comparison in timezone checking

The original condition incorrectly returned -1 when the real path and the
provided pathname matched, due to a flawed use of `g_strcmp0`. This patch
corrects the logic to return 0 (success) when the paths match, ensuring
proper file comparison behavior.
