Use lua current version (not lua5.1) for all fedora builds.

There are strange things hardwired in FindThirdPartyLua.cmake. Lua 5.1 is forced on windows and "unix if not fedora21". On recent fedora (tested with fedora 28/29), this (legacy?) library does not contain lua_setglobal (it seems it is contained in ubuntu lua5.1). FindThirdPartyLua.cmake has a "hardwired" correction for the specific version of fedora 21 (which is ~4 years old). Corrected by applying the fix to all fedora distributions (it currently selects lua5.3.so which indeed contains the lua_setglobal symbol).
