libc: Remove futimens() and utimensat() compat stubs.

Browse Source 
The futimens() and utimensat() compat stubs allowed using these functions on
kernels that did not have the system calls yet (10.2, old 11-current).

Also remove the documentation of the [ENOTSUP] error that could occur with
an old kernel.

A -DNO_CLEAN build may fail because the depend files refer to the deleted
files.
