selftests/cgroup: Remove redundant cg_enter_current() call in test_core

Browse Source 
The test_cgcore_no_internal_process_constraint_on_threads test has two
back-to-back cg_enter_current(root) calls in its cleanup path.

A single cg_enter_current() call atomically migrates the entire thread
group to the target cgroup even for multi-threaded processes, and this
test creates no extra threads or child processes that would require a
second migration attempt. The second call is a harmless no-op once the
process is already in the root cgroup, but it is redundant and
inconsistent with the cleanup logic used in all other cgroup core
selftest cases.

Remove the duplicate call to clean up the code. No functional change is
intended.
