cmake: Remove pagezero_size from linker options

Previous versions of LuaJIT required setting linker options
-pagezero_size and -image_base.  This was accomplished in commit
c9224edbad, but as of LuaJIT 2.1, this is no longer necessary, and
doing so results in the application being killed when run natively
on macOS ARM targets.
