Update how we search for Lua with pkg-config.
First, search for packages with the version number without the period (bug 11219). Second, don't look for Lua 5.3 because we don't work with it. If what we find (without pkg-config's help) is Lua 5.3, disable Lua support (bug 10881). Cmake support by Peter Wu (originally Ie73e5b53640f10432881a9671c0a605f7f027ed8): Note the check for "lua<=5.2.99" instead of "lua<5.3" since cmake does not support the latter syntax. Tested with lua5.2, lua5.1 and lua (5.3) installed.
