[gnome-software] Remove margins in the History dialog

[Kalev Lember <klember src gnome org>]

commit c0248c9eacb6438ef3a0048846e3b165df11fc74

    Remove margins in the History dialog
    
    Remove unnecessary margins, shadows, borders, frames etc. to unify
    the appearance of this dialog box with the main application window.
    Basically the same as commit 5ee44644c702db91dad20b7d572c1a2c9460e48f
    but this dialog has been forgotten.
