[LTP] [PATCH] controllers/libcpuset.c: Add 'cpuset' prefix for cpuset files

[Xiao Yang]

cpuset_cpusetofpid() in cpuset_cpu_hog.c cannot find cpuset files by
wrong names(without 'cpuset' prefix) so cpuset_load_balance_test.sh
reported the following error:
---------------------------------------
cpuset_load_balance 1 TFAIL: load balance test failed.
---------------------------------------

Use correct names(with 'cpuset' prefix) to find cpuset files.

Fixes: #690
