__fish_prepend_sudo: Toggle "sudo" on multiple presses (#7012)

Browse Source 
At the moment calling __fish_prepend_sudo multiple times does not toggle
sudo, and also unnecessarily uses the `-c` flag to `commandline` to see if
the first token on the commandline is "sudo".

This change removes the `-c` switch and also toggles "sudo" on multiple
calls to __fish_prepend_sudo, while maintaining the cursor position and
while maintaining any spaces between "sudo" and the next token on the
commandline.
