With newer newlib we get a build error with mqueue.h realted to mode_t.
Let's just let newlib define mode_t and have minimal libc also define
it in sys/types.h. So we remove the duplicated definition in
posix/unistd.h.

Both SDK 0.10.0-beta2 and the ARM gcc 2018q2 run into a build issue with
newlib and conflict definitions of mode_t type.
First we need to add some ifdef protection if mode_t is already defined
and set _MODE_T_DECLARED if we are the first to define it.
Secondarily, we rename include/posix/sys/types.h to
include/posix/posix_types.h so that we aren't getting a name collusion
with the system sys/types.h and that we can easily and clearily include
it (which we need to do to pull in the info from newlib).

Don't duplicate definitions.
This fixes build errors due to redifinitions of preprocessor symbols.

Move posix layer from 'kernel' to 'lib' folder as it is not
a core kernel feature.
Fixed posix header file dependencies as part of the move and
also removed NEWLIBC related macros from posix headers.
