I wish we did not use a crazy phrase "path suffix", that would
inevitably confuse ourselves with things like ".exe".

i.e. this is offset to the last path component.

Perhaps

    static ssize_t last_path_component_offset(const char *path, const char *name)

I am tempted to also call the second parameter to this function
"basename", as we know from the proposed log message that you wish
"basename" were usable for this purpose, but basename itself has
another confusing factor (i.e. "are we stripping ".exe" extension?",
to which the answer is no in the context of these functions).

If we agree with the "last path component" phrasing, has_path_suffix()
would become something like:

    int last_path_component_equals(const char *path, const char *name);

perhaps.
