Attribute certificates are generally using RSA-SHA1 or RSA-SHA256
signatures, so include those. In addition, the CA signing restrictions
imposed for general purpose certificates don't apply here - drop that
restriction from certificate signature validation.
golint current generates complaints:
var oidTpmIdLabel should be oidTpmIDLabel
var oidTcgPlatformManufacturerIdV2 should be oidTcgPlatformManufacturerIDV2
var oidTcgPlatformConfigUri should be oidTcgPlatformConfigURI
Update names to satisfy golint.

Updates #131
Platform certificates are defined as RFC5755 attribute certificates with
various additional attributes and extensions defined in the TCG Platform
Certificate Profile. Add support for parsing them, derived from
crypto/x509. Include some test certificates and verify we parse them.
