uprobes/core: Move insn to arch specific structure

Browse source 
Few cleanups suggested by Ingo Molnar.

- Rename struct uprobe_arch_info to struct arch_uprobe.
- Move insn from struct uprobe to struct arch_uprobe.
- Make arch specific uprobe functions to accept struct arch_uprobe
  instead of  struct uprobe.
- Move struct uprobe to kernel/uprobes.c from include/linux/uprobes.h
