kernel: Allow SYS_KERNEL_VER_MAJOR(), etc. return full range of values.

Browse source 
Macros SYS_KERNEL_VER_MAJOR(), SYS_KERNEL_VER_MINOR(),
SYS_KERNEL_VER_PATCHLEVEL() capped their return values to 0-15 range,
even though documentation says "Each of these elements must therefore be
in the range 0 to 255, inclusive". Fix to corresponds to the docs. This
issue especially affected SYS_KERNEL_VER_PATCHLEVEL(), which could be
set to a high value to represent WIP code in-between releases.
