Use a more secure command line building method
Previously, a command is built by string concatenation. Here, the distinction between a value and multiple params got lost. Solve this by using an array for shell arguments. As the escaping is now removed from the `rrd_gen_graph` function, the canvas style needs to manually add those quotes to make the JS code still work. That only supports double-quotes, so hopefully nobody creates a name with a double quote as that would break the fragile JS command line parser. Separate the rrdtool options from the rrdtool graph command to make the `$graph_type == 'canvas'` option work (it would otherwise not understand the `rrdtool graph - -a PNG` option). Merge the SVG and PNG cases as they are the same except for the Content-Type header. Fix a missing html escape in a debug style.
