[gambit-list] Move definitions of string=? and string-ci=? to _system.scm

Marc:

The tables implementation has special hash functions for these common  
tests:

eq?, eqv?, equal?, string=?, string-ci=?

The table access routines and the special has functions are defined  
in _system.scm.

The tests themselves are defined in the following:

_system.scm: eqv?, eq?, equal?
_std.scm: string=?, string-ci=?

So tables that use string=? for a hash function have to do two extra  
intermodule calls per table lookup; that may be why string=? tables  
are currently noticeably slower than eq? tables.
