Hou Tao 441c725ed5 selftests/bpf: Close cgrp fd before calling cleanup_cgroup_environment() ...

There is error log when htab-mem benchmark completes. The error log
looks as follows:

$ ./bench htab-mem -d1
Setting up benchmark 'htab-mem'...
Benchmark 'htab-mem' started.
......
(cgroup_helpers.c:353: errno: Device or resource busy) umount cgroup2

Fix it by closing cgrp fd before invoking cleanup_cgroup_environment().
