libbpf: Ensure libbpf always opens files with O_CLOEXEC
Make sure that libbpf code always gets FD with O_CLOEXEC flag set,
regardless if file is open through open() or fopen(). For the latter
this means to add "e" to mode string, which is supported since pretty
ancient glibc v2.7.
Also drop the outdated TODO comment in usdt.c, which was already completed.
