browse-url's xdg-open detection was too picky on some GNU/Linux

if it is executable, as nowadays this is more likely to be correct than
trying to use heuristics from a few years ago. Don't test for nohup: it
is ineffective nowadays, as xdg-open's child uses the default action for
SIGHUP even if xdg-open's invoker ignores SIGHUP. While we're at it,
