Fix invocations of LOG missing format string argument

Fix invocations of LOG missing format string argument

First argument of LOG* macros is passed to sd_journal_print() as format string.
In some places these macros were used with no format string at all, simply
passing e.what() from an exception. This could lead to a format string
vulnerability in the code, potentially allowing arbitrary code execution.
This error also caused build break:
