hw-breakpoints: Fix misordered ifdef

Fix a misplaced ifdef. We need the perf event headers also in
off-case to avoid the following build error:

 include/linux/hw_breakpoint.h:94: error: expected declaration specifiers or '...' before 'perf_callback_t'
 include/linux/hw_breakpoint.h:102: error: expected declaration specifiers or '...' before 'perf_callback_t'
 include/linux/hw_breakpoint.h:109: error: expected declaration specifiers or '...' before 'perf_callback_t'
 include/linux/hw_breakpoint.h:116: error: expected declaration specifiers or '...' before 'perf_callback_t'
