completion: protect prompt against unset SHOWUPSTREAM in nounset mode

As it stands, the only call site of `__git_ps1_show_upstream` checks
that the `GIT_PS1_SHOWUPSTREAM` variable is set, so this is effectively
a no-op. However, that might change, and chances of noticing the
unprotected use might not be that high when it does.
