QSslCertificate::fromPath fix wildcard handling

The reqExp used to handle wildcards in the path was broken. So we
always searched the working directory and not the specified path.
Autotest where passing because of a hack used for Windows paths
where we removed the first two chars in the path string.

This fix will not use nativeSeparators thus removing the Windows hack
and fix the regExp to match wildcard chars.
