Subject: [PATCH] ID:322 - let 'ekanalyzer frushow' run without a working IPMI
 target

Commit changes a dummy interface in a way that it acts as a dummy interface when
no IPMI_DUMMY_SOCK env variable is set. Therefore, it's possible to run
'ekanalyzer frushow' without having BMC. Still, you need to specify this IPMI
interface.
If IPMI_DUMMY_SOCK is set, then dummy interface will work as it was working
before.
