pythia8:: nosystem have no effect and system installed pythia8 is used

[adriansev]

Hi guys! @TimoWilken @ktf It seems that nosystem argument of alibuild does not affect pythia8 recipes and the system provided one is used ..

2022-12-19@14:34:34:DEBUG:O2:O2:flow_lhc22: ninja: error: '/usr/lib64/libpythia8.so', needed by 'stage/lib64/libO2Generators.so', missing and no known rule to make it

this is after i removed pythia8-devel package after first clean build of O2, so it would seem that is taken and written in some other package
