libbpf: Set close-on-exec flag on gzopen
Enable the close-on-exec flag when using gzopen. This is especially important
for multithreaded programs making use of libbpf, where a fork + exec could
race with libbpf library calls, potentially resulting in a file descriptor
leaked to the new process. This got missed in 59842c5451fe ("libbpf: Ensure
libbpf always opens files with O_CLOEXEC").
Fixes: 59842c5451fe ("libbpf: Ensure libbpf always opens files with O_CLOEXEC")
