all: fix the format string exceptions
Currently, there are possibilities in few places, where a user-controlled
(like filename, program parameter etc) string can be passed as 'fmt' for
printf(), which can lead to segfault, if the user's string contains '%s',
'%d' in it.
While fixing it, makes sense to make the explicit check for such issues
across the codebase, by making the format call properly.
Fixes: CVE-2018-14661
Fixes: bz#1644763
