- Change postinstall scripts to run ldconfig directly

- Update to version 8.210:
+ Bug fix in CKKW-L merging for LHE files, such that the
factorization and renormalization scales are set by the SCALUP
value if the muf2 and mur2 LHEF3 attributes have not been set,
and the user has not set any explicit values; this change
restores the PYTHIA 8.1 behaviour.
+ Various technical improvements in the machinery for hard
diffraction.
+ Correct quark flavour selection when a string spanned directly
between two junctions is split up.
+ Check that SK-I and SK-II colour reconnection machineries only
are called for event topologies they are set up to handle.
+ Bug fixes in partial widths of the W' boson. Results are
correct when the W' is a simply rescaled copy of the W, but
not for more general couplings. Thanks to Mihail Chizhov.
+ Minor fix in default location of PDF data files in the
constructors. No practical consequence since correct
non-default values are used.
+ Tiny fix in the configure script, so that CXX options
containing an equal sign are parsed correctly.
- Changes from version 8.202 through 8.209:
+ See /usr/share/doc/packages/pythia/htmldoc/UpdateHistory.html.
- Add pythia-makefile-destdir-support.patch to enable DESTDIR
support in the Makefile; makes configure stage buildroot-free
and prevents an ugly BUILDROOT trace in the shlib.
- Enable additional bindings now that all necessary deps are in
Factory; new subpackage: libpythia8lhapdf6.
- Add BuildRequires: chrpath; required to cleanup rpath in
