bpf: Check flags for branch stack in bpf_read_branch_records helper
Recent commit [1] changed branch stack data indication from
br_stack pointer to sample_flags in perf_sample_data struct.
We need to check sample_flags for PERF_SAMPLE_BRANCH_STACK
bit for valid branch stack data.

Fixes: a9a931e26668 ("perf: Use sample_flags for branch stack")
