    win32: remove workaround for font backend
    
    It turns out that explicitely setting font backend on win32
    is only useful for pygobjectwin32 PangoCairo builds because
    in vanilla PangoCairo win32 backend is default on windows and
    changing default to fontconfig was patch included in pygobjectwin32 since
    >16/4/2015 rev16:
    >- PangoCairo: favor fontconfig over win32 fontmap by default,
    >this would overcome "Pango Warning:... expect ugly output"
    
    Recent libraries update in msys2-mingw64 breaks current code
    (according to https://github.com/Alexpux/MINGW-packages/pull/3611
    the breakage reason is PangoCairo.Win32FontMap being private)
    
    While meld code can be modified to use non-private API it looks
    unneeded since meld requires gtk 3.20 and pygobjectwin32 builds stalled
    with gtk 3.18 and can't run current meld 3.19+
    
    So font backend setting is removed.
    Also package presence check is removed
    since there in no other explicit uses in meld.
