SvStream: remove the error prone operator<</>>(sal_Int64)

As the recent regression after merging AOO patch adding code serializing
"long" variables has shown, this overload (which was added in
7b2a0e541567be9750dfc7d98374555967da3470) is a bad idea.

In a unxlngx build, nm finds uses of the symbols _ZN8SvStreamrsERl
and _ZN8SvStreamlsEl in these files:

- sbxvalue.cxx: this appears to be a legitimate use with sal_Int64

- dateitem.cxx: this was accidentally changed by commit
  9830fd36dbdb72c79703b0c61efc027fba793c5a

- atrfrm.cxx: this was added for Table Autoformat enhancement in
  7e8c0bd73ee59ff3041e55268c77203373962e51, which is after the
  sal_Int64 operators were added, so the file format is now
  platform dependent
