bpf: fix perf_snapshot_branch_stack link failure
The newly added code to handle bpf_get_branch_snapshot fails to link when
CONFIG_PERF_EVENTS is disabled:
aarch64-linux-ld: kernel/bpf/verifier.o: in function `do_misc_fixups':
verifier.c:(.text+0x1090c): undefined reference to `__SCK__perf_snapshot_branch_stack'
Add a build-time check for that Kconfig symbol around the code to
remove the link time dependency.
Fixes: 314a53623cd4 ("bpf: inline bpf_get_branch_snapshot() helper")
