send-email: do not reverse the command line arguments

The loop picks elements from @ARGV one by one, sifts them into arguments
meant for format-patch and the script itself, and pushes them to @files
and @rev_list_opts arrays.  Pick elements from @ARGV starting at the
beginning using shift, instead of at the end using pop, as push appends
them to the end of the array.
