[PATCH 10/11] exec: Restrict ramblock.h to sysemu/

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

To make it clearer the ramblock.h header is sysemu specific,
move it to the sysemu/ directory.

Patch created mechanically using:

  $ sed -i s,exec/ramblock.h,sysemu/ramblock.h, $(git grep -l exec/ramblock.h)

Then the #ifdef'ry conditional on CONFIG_USER_ONLY has
been replaced by an #error.
