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.
