Public bug reported:

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.
