Remove sage -twistd from src/bin/sage

[jhpalmieri]

There is no twistd executable anymore, since the twisted package is being removed in #29754. So let's remove the corresponding command-line option to sage.

By the way, for a separate ticket: the OS X app could use some attention. If I run git grep twistd src, I see

src/mac-app/AppController.m:    NSString *pidFile = [@"~/.sage/sage_notebook.sagenb/twistd.pid" stringByStandardizingPath];
src/mac-app/English.lproj/MainMenu.nib/designable.nib:                                        <menuItem title="twistd" id="1456">
src/mac-app/English.lproj/MainMenu.nib/designable.nib:                                        <menuItem title="twistd" id="1603">
Binary file src/mac-app/English.lproj/MainMenu.nib/keyedobjects.nib matches
src/mac-app/sage-is-running-on-port.sh:if [ ! -e "$PID_FILE" ] && [ -e ~/.sage/sage_notebook.sagenb/twistd.pid ]; then
src/mac-app/sage-is-running-on-port.sh:    PID_FILE=${1-~/.sage/sage_notebook.sagenb/twistd.pid}
src/mac-app/sage-is-running-on-port.sh:    if [ ! -e "$PID_FILE" ] && [ -e ~/.sage/sage_notebook.sagenb/twistd.pid ]; then
src/mac-app/sage-is-running-on-port.sh:        PID_FILE=${1-~/.sage/sage_notebook.sagenb/twistd.pid}

I don't know anything about Mac apps, so I don't know if this is anything to be concerned about.
