[PATCH] make tty_insert_flip_string a non-GPL export

Alan sayeth "Based on Linus original comments about _GPL we should export
tty_insert_flip_char as EXPORT_SYMBOL because it used to be EXPORT_SYMBOL
equivalent (trivial inline).  The other features are new extensions are were
not available to drivers before so need not be provided except as _GPL
functionality as far as I can see."
