[gnome-continuous-yocto/gnomeostree-3.28-rocko: 3023/8267] sqlite3: Revert ad601c7962 from 3.14.1 amalgamation package

    sqlite3: Revert ad601c7962 from 3.14.1 amalgamation package
    
    It turns out this change between 3.12.2 and 3.13 introduces
    a 2% increase of build time based on statistic data in
    bz10367.
    
    The added patch is forged by diffing the new sqlite3.c
    generated from reverting the change in raw source of sqlite3
    project, and then manually migrate the delta to a sqlite3.c
    from the 3.14.1 tarball package because what recipes reference
    is actually a generated C code (amalgamation) release package
    and we cannot apply the real change to 3.14.1 cleanly due to
    so many changes happened.
    
    Fixes [YOCTO #10367]
