fast-export: rename --signed-tags='warn' to 'warn-verbatim'
The --signed-tags= option takes one of five arguments specifying how to handle signed tags during export. Among these arguments, 'strip' is to 'warn-strip' as 'verbatim' is to 'warn' (the unmentioned argument is 'abort', which stops the fast-export process entirely). That is, signatures are either stripped or copied verbatim while exporting, with or without a warning. Match the pattern and rename 'warn' to 'warn-verbatim' to make it clear that it instructs fast-export to copy signatures verbatim. To maintain backwards compatibility, 'warn' is still recognized as deprecated synonym of 'warn-verbatim'.
