util/gen_xmlpool: Use more standard style

gen_xmlpool uses a style unlike the rest of mesa, spaces between
function/method calls and the parens, strange whitespace to force lining
up method calls, and some other whitespace stuff. Since I'm going to be
doing some work in the file, I'm going to start cleaning those up.
