Remove redundant file info from SM dlog logs

Remove redundant file info from SM dlog logs

Security-manager uses code adapted from DPL for logging. Currently
a dlog backed is utilized. Both DPL and dlog include information
like file name, line and function from where the log was triggered.
It lead to redundant file info in logs.

In order to remove this redundant information, dlog macro SLOG was
replaced with the macro called print_system_log. The print_system_log
macro does not add its own set of information (it displays only
a message prepared by the developer). The print_system_log macro is
labeled as an 'internal' in dlog-internal.h header file but in this
case 'internal' means that macro should not be used by applications
but may be used by system/platform deamons.

Also the FormatMessage was modified in order to display a log message
in a dlog style.
