hw-breakpoints: Fix build on !perf architectures
the arch/alpha build fails with:
In file included from tip/kernel/exit.c:52:
tip/include/linux/hw_breakpoint.h: In function 'hw_breakpoint_addr':
tip/include/linux/hw_breakpoint.h:21: error: 'struct perf_event' has no member named 'attr'
[...]
Move these helper inlines inside the CONFIG_HAVE_HW_BREAKPOINT ifdef.
