Bug description:
Description: hypfs: fix listing z/VM guests with access control
group set
Symptom: hypfs/hyptop info doesn't include z/VM guests with access
control group set
Problem: Currently if z/VM guest is allowed to retrieve hypervisor
performance data globally for all guests (privilege class B)
the query is formed in a way to include all guests but the
group name is left empty. This leads to that z/VM guests
which have access control group set not being included in
the results (even local vm).
Solution: Change the query group identifier from empty to "any"
to retrieve information about all guests from any groups
(or without a group set).
Reproduction: Run hyptop under z/VM from a guest with privilege class
B and some guest(s) with RACF/ACI groups set.
