KEYS: trusted: fix TPM trusted keys for generic framework

The generic framework patch broke the current TPM trusted keys because
it doesn't correctly remove the values consumed by the generic parser
before passing them on to the implementation specific parser.  Fix
this by having the generic parser return the string minus the consumed

Additionally, there may be no tokens left for the implementation
specific parser, so make it handle the NULL case correctly and finally
fix a TPM 1.2 specific check for no keyhandle.
