- update to v1.2.2:
  * fix a regression in perf tool caused by libbpf resetting its custom
    catch-all SEC() handler on explicit bpf_program__set_type() call
  * fix possible double-free in USDT-related libbpf code, which happens when
    libbpf runs out of space in __bpf_usdt_specs map due to having too many
    unique USDT specs

Remove requirement of linux-glibc-devel >= 5.16 for devel package

They're no longer needed since libbpf v0.7, which includes commit 8404d1396c "libbpf: Define BTF_KIND_* constants in btf.h to avoid compilation errors" that defines the constants that used to be missing.
