[PATCH 4/4] build: visibility=default for library structs is no longer needed

[Jani Nikula]

Commit d5523ead90b6 ("Mark some structures in the library interface
with visibility=default attribute.") fixed some mixed visibility
issues with structs. With the symbol default visibility reversed, this
is no longer a problem.
