perf bench breakpoint: Fix build on 32-bit arches
Cast pointers to unsigned long instead of to uint64_t to avoid this
problem on 32-bit arches:
31 6.89 debian:experimental-x-mips : FAIL gcc version 11.2.0 (Debian 11.2.0-18)
bench/breakpoint.c: In function 'breakpoint_setup':
bench/breakpoint.c:56:24: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
56 | attr.bp_addr = (uint64_t)addr;

make[3]: *** [/git/perf-5.18.0-rc7/tools/build/Makefile.build:139: bench] Error 2
