Tweak SOL log checking for IPMI sol testing

Fixes:
     - Keyword renamed.
     - Split the SOL checking for hostboot message and ISTEP.

There is also a known ipmitool for SOL which impacts the test as well.
Reference bugzilla: https://sourceforge.net/p/ipmitool/bugs/495/

Resolves  openbmc/openbmc-test-automation#1158
