Fix memory leakages when btf_node or bpf_prog_info_node is duplicated
during insertion into perf_env.

v1 -> v2:
- Following Namhyung's review suggestions, optimize patch 3 by removing
  initialization of the return value to true. Instead, use the internal
  function's return value directly and add a blank line between the
  declaration and other statements.
- Add a blank line before the return statement.
- Following Namhyung's review suggestions, fix the incorrect Fixes tags
  for all three patches.
- Link to v1: https://lore.kernel.org/all/20241128125432.2748981-1-quic_zhonhan@quicinc.com/
