Fix showupstream behavior in __fish_git_prompt

Browse source 
The __fish_git_prompt_show_upstream helper function was inadvertently
looking at the misnamed variable __fish_git_prompt_show_upstream in some
cases, including when implementing the bash.showUpstream override.
Fixing the script to use __fish_git_prompt_showupstream triggered an
infinite loop because the --on-variable hook does not distinguish
between local and global variables.

Update the script to set a completely different local variable to
__fish_git_prompt_showupstream and to override this local variable for
bash.showUpstream.

Also update the code that looks at bash.showUpstream to also read
bash.showupstream, because the bash script appears to have a bug where
it looks for bash.showupstream despite documenting bash.showUpstream.
