win32: Use CertOpenStore instead of CertOpenSystemStore

CertOpenSystemStore is not available when building for windows store.
Both functions are available since windows XP, so there is no
compatibility change.
CertOpenSystemStore documentation states "Only current user certificates
are accessible using this method, not the local machine store." hence we
pass CERT_SYSTEM_STORE_CURRENT_USER.
We also use the wide chars variants, in the event the ansi ones are
silently rejected by windows store applications (which is not
documented, but which I strongly suspect)
This is equivalent to Wine's implementation of CertOpenSystemStore:
