[PATCH 1/2] test-logging: Fix -Werror=maybe-uninitialized warning

[mrezanin]

From: Miroslav Rezanina <address@hidden>

Checking for uninitialized variables raises warning for file path
variables in test_logfile_write and test_logfile_lock functions.

To suppress this warning, initialize varibles to NULL. This is safe
change as result of g_build_filename is stored to them before any usage.
