Newlib libc already provides sys/stat.h, so trying to have sys/stat.h
on the level of POSIX subsys inevitable leads to include order and
definition conflicts. Instead (as most of other sys/* includes)
should come from the underlying libc.
While moving, made unrelated change of removing #include <kernel.h>,
to accommodate the change reviewers.

Some third-party components include this file without really needing
any symbols from it. Presence of this file allows to build them
against minimal libc, whereas previously they forced Newlib.
