[devhelp] build: have only one PKG_CHECK_MODULES

[Sébastien Wilmet <swilmet src gnome org>]

commit cfc040dab50d8157d828bdf89fafbd24446c6ee6
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Thu Nov 3 15:17:05 2016 +0100

    build: have only one PKG_CHECK_MODULES
    
    To list dependencies only once. The devhelp program (not the library)
    has the same dependencies as the library.
    
    Also, remove gthread because it isn't used by devhelp.
    
    And update version numbers to stable versions.
