[scan-build-py] Fix exception on shutdown with sarif-html output format

When running scan-build-py's analyze-build script with output format set
to sarif & html it wants to print a message on how to look at the
defects mentioning the directory name twice.

But the path argument was only given once to the logging function,
causing "TypeError: not enough arguments for format string" exception.
