[libxslt] Remove redundant flags from pkg-config files

[Nick Wellnhofer <nwellnhof src gnome org>]

commit da2f90ba4bc438e39304666b170c3e199b281bb2

    Remove redundant flags from pkg-config files
    
    Flags for dependencies are automatically pulled in by "Requires".
    There's no need to list them separately.
    
    Add libxslt as requirement of libexslt.
    
    Fixes #53.
