Fix wrong dump output of *Info#flags

Fix wrong dump output of *Info#flags

This CL follows up to a previous CL [1] that introduced an ability to
control filtering level of
 - ActivityInfo#dump()
 - ApplicationInfo#dump()
 - ComponentInfo#dump()
 - ProviderInfo#dump()
 - ResolveInfo#dump()
 - ServiceInfo#dump()
but also masked following outputs as an unexpected side effect.
 - ActivityInfo#flags
 - ApplicationInfo#flags
 - ProviderInfo#flags
 - ServiceInfo#flags

With this CL, above *Info#flags are correctly dumped again.
