Compile warning (and potential segfault) after merge from calve/do_not_show_diff

[vikman90]

When I compile the master branch I get the following warning:

config/syscheck-config.c: In function ‘Read_Syscheck’:
config/syscheck-config.c:751:21: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘char **’ [-Wformat=]
                     verbose("Set nodiff regex: %s", syscheck->nodiff_regex[nodiff_size]->patterns);

Indeed, syscheck->nodiff_regex[]->patterns is a pointer to a matrix and might raise a segmentation fault if was read as a string.

This issue is caused by the commit d8a57c4 (pull request #765).

Issue solved with merge #781. Thanks!
