pmdaproc: fix cgroup cpu metrics refresh structures
Jan Kurik encountered this issue when running the regression
testsuite (especially qa/359) on non-x86_64 architectures.
Something must've changed in the toolchain recently on these
platforms since we've not seen this before, but this bug has
been in our code for some time. It works everywhere else by
good fortune, when there just happen to be NULLs after these
cgroups CPU parsing data structures.
Resolves Red Hat BZ #2081262.
