libutils: prefix system header guard with 2 underscore chars

Adds prefix "__" to standard header files implemented in libutils. This
is applicable as these header guards macro are system macros. This
change prevents conflicts with external component as faced with
SCP-firmware [1] that implements wrapper headers with #include_next for
assert.h and stdlib.h using ASSERT_H [2] and STDLIB_H [3] as header
guards as in libutils.

Prior this change did stdint.h both define STDINT_H and _STDINT_H but
guards only upon STDINT_H. This change removes STDINT_H.
