[Tizen] Check signature value using xmlsec1 library

Based on API provided by xmlsec1 library, signature value and reference are checked.
The codes are for init libxslt library. And there is a macro above comment:
ifndef XMLSEC_NO_XSLT
And prototype of function xsltSetSecurityPrefs is as below:
int	xsltSetSecurityPrefs		(xsltSecurityPrefsPtr sec, 
					 xsltSecurityOption option, 
					 xsltSecurityCheck func)
In the third parameter, we use xsltSecurityForbid() function, which is used to always forbid an operation.
