[PATCH -tip ] kprobes: Move __kprobes definition into compiler.h

[Masami Hiramatsu]

Currently, __kprobes is defined in linux/kprobes.h which
is too big to be included in small or basic headers
only for using this attribute.

This moves __kprobes definition into linux/compiler.h
in which other compiler attributes are defined.
