Assume that we have functional, 64-bit fseeko()/ftello().

Browse Source 
Windows has this, and so do all other live platforms according to the
buildfarm, so remove the configure probe and src/port/ substitution.

Keep the probe that detects whether _LARGEFILE_SOURCE has to be
defined to get that, though ... that seems to be still relevant in
some places.

This is part of a series of commits to get rid of no-longer-relevant
configure checks and dead src/port/ code.  I'm committing them separately
to make it easier to back out individual changes if they prove less
portable than I expect.
