To implement CertVerifyProc on Android we refer to the Java 
side to query the platform trust managers. Currently the 
information we get from the platform is binary - each 
certificate chain is either identified as trusted or not, in 
which case we assume that this is due to not-trusted root.

This patch provides better granularity distinguishing the 
following cases: expired, not yet valid, incorrect (could not 
be parsed), not trusted root.

This allowed to reenable two net unittests:
- CertVerifyProcTest.ExtraneousMD5RootCert
- CertVerifyProcTest.IntermediateCARequireExplicitPolicy

The following net unittest had to be disabled as it joins 
the club of CertVerifyProc tests failing on bots with 
incorrect time/date settings:
- CertVerifyProcTest.InvalidKeyUsage
