Database: Clean up the post_category column removed from DB schema for new installations in WordPress 2.8.

Browse Source 
Its presence may conflict with `WP_Post::__get()`, which should generally fill the non-existent `post_category` property, but is not triggered if the column exists in the database.

Follow-up to [10895].

Props leogermani, davidbaumwald, hellofromTonya.
Fixes #51288.
