core-util: Make pa_make_secure_dir() act like mkdir -p

Browse source 
This makes pa_make_secure_dir() create any missing parent directories in
the given path as well. This is useful, for example, on a pristine
system with a clean $HOME that needs ~/.config/pulse/ to be created when
~/.config does not exist.
