d28677795e [NTOSKRNL] Restore section layout for NTOSKRNL to fix BSOD regression CORE-14683
This version (after .rsrc) works different than the
proper version I used for 0.4.12 (after .reloc).

Inserting after .rsrc is actually not correct, but Thomas believes it can
be used as a temporary trick to avoid random memory corruption upon
relocations of the kernel, caused by ROSBE-154.

I follow his advice, although when judging from practical tests only:
as long as we limit this script to NTOSKRNL like I do for releases
there have no negative consequences been observed in real life yet
even with the proper version of 0.4.12.
Up to now those problems have only been observed when used for drivers
MODULE TYPE sdk/cmake/gcc.cmake as well, like
it was tried for a moment in master 0.4.13-dev-609-g
c4d8e2a6e9

Using for drivers immediately did lead to BSODs like CORE-16183 and therefore was
mitigated in master by total disabling of the scripts for both,
kernel and drivers in
0.4.13-dev-621-g
36e9a6f8dd

To allow installing DVDWritenow without BSOD,
we need the script at least for ntoskrnl!

I committed this patch (after .rsrc) already into 0.4.13RC and 0.4.14RC.

[CMAKE] Ensure the INIT section is placed at the end of a module. CORE-14683
For MSVC, marking the section as discardable will do this automatically.
For GCC, we use a linker script that places it after the .reloc section
(which should be the last "real" section, check ld --verbose output for the
default linker script).

This fixes what seems to be a regression from r55835 (!).
