Hi!
I realized I forgot to add some refs to related issues,
so here is the new version of the commit message:
====================================================
test: adapt disabled tests from PUC-Rio
 
Version and status are printed in stdout instead stderr
since LuaJIT-2.0.0-beta11 (as it is not an error message). This behavior
is the same as in Lua 5.2, so necessary changes in tests can be
adapted from PUC-Rio Lua 5.2 test suite.
 
Closes tarantool/tarantool#5687
Part of tarantool/tarantool#5845
Part of tarantool/tarantool#4473
====================================================
 
Best regards,
Maxim Kokryashkin
