patchbomb: protect email addresses from shell

When patchbomb sends email via a sendmail-like program it invokes this
using procutil.popen which passes the string to a shell to be parsed.
To protect any special characters in the email addresses on the
command line from being interpretered by the shell they must be
quoted.
