um: fix call tracer and bug handler
Commit 1de1502c ("x86, um: now we can get rid of trivial uml headers")
removed accidentally bug.h which broke UML's call tracer and bug
handler.
Without asm-generic/bug.h UML uses BUG() from arch/x86/ which makes use
of ud2. UML cannot use ud2, it raises SIGILL in user mode. As UML has
a different stack for handling signals the call trace will be cut off.
