uml: arch/um/include/init.h needs a definition of __used

init.h started breaking now for some reason.  It turns out that there wasn't a
definition of __used.  Fixed this by copying the relevant stuff from
compiler.h in the userspace case, and including compiler.h in the kernel case.

[xiyou.wangcong@gmail.com: added definition of __section]
