Fix boost process call for SEL Clear again

The boost::process::seach_path() call to find journalctl caused the
library to fail to register the OEM IPMI commands.  This change
uses the hardcoded path to journalctl instead.

Tested: Verified that the OEM commands are getting registered from
the library and that SEL Clear executes the journalctl call.
