For historical reasons, mainly. But nowadays standards have settled in a
way that it doesn't make sense to pack even more into libc than currently
is. As of now, libc concerns itself with some string handling, (float,
double) numeric functions and (the biggest part) operating system
interface. And that's already a tall order, mind you :-)

See [1] for a good overview on what is there and how it came to be.

As far as I know there are no "standard" libraries for the classical
algorithms and data structures in C, although if you look around you'll
find many good implementations as spin-off of several projects.

The C++ folks have gone some way into standardizing this (cf. STL [2]),
perhaps because in C++ it's somewhat easier to express generic
algorithms.
