Prevent `ctags-update` package from nagging for TAGS generation

Recent update in `ctags-update` package has made it mandatory to have a TAGS
file. I do not want that. This commit prevents the TAGS generation nag if
`ctags-update` is called non-interactively i.e. via `after-save-hook`.

If TAGS generation is **necessary**, do M-x ctags-update i.e. call that function
interactively.
