[jansson] Don't use WinCryptoApi for UWP builds

Browse Source 
Jansson tries to use Windows' CryptoApi to seed its hash table. This API
is not exposed in UWP, but there is still a fallback to use current time
and PID.

This change makes Jansson use less-secure fallback, but fixes
compilation for UWP target.
