ntdll: move relocations from mapping into loader
while writing test for some mem mapping functions i found that
the relocation should happen in the loader and not in NtMapViewOfSection
http://www.codeguru.com/forum/archive/index.php/t-376151.html describes this a bit
still quite hackish it changes protections of each section in the image
without checking if it is even needed
need to check if "oep points into data section check" is supposed to happen inside NtMapViewOfSection
or later in the loader
