test_cpuset_prs.sh is failing with the following error:

test_cpuset_prs.sh: line 29: [[: 8 57%: syntax error in expression (error token is "57%")

This is happening because `lscpu | grep "^CPU(s)"` returns two lines in some systems (such as Debian unstable):

# lscpu | grep "^CPU(s)" CPU(s): 8 CPU(s) scaling MHz: 55%

This is a simple fix that discard the second line.
