httpd: improve error message for missing browser — heartwood

If open or xdg-open fail the error is:

No such file or directory (os error 2)

This generally means that the command could not open the browser on the OS. To provide better help, improve the error message by informing the user what went wrong and that they can run rad web --no-open instead.
