correct edje pkg-config generation for luaold

Currently, edje.pc gets its lua Requires from the -Dlua-interpreter argument.
If -Dlua-interpreter=lua, an unversioned lua entry ends up in Requires, which
cannot always be satisifed.  The evas filters meson.build handles this case by
generating a version-specific entry.  This patch copies that logic into the top
level meson.build, and passes the result to the edje subproject.
