Subject: [PATCH] erl: Set -noshell when -S is used

Since the primary intended usecase for -S is command-line scripts such
as the new "httpd serve", automatically add the "-noshell" flag to
simplify noninteractive use.

Remove a leading newline from the httpd serve startup output that was
used to separate it from the shell prompt.

As suggested in #7470.
