tpm2 git AUTOREV fix for BB_NO_NETWORK

Bitbake will try an ls-remote for any recipe whose SRCREV is AUTOREV,
even if that recipe will not ultimately be used for a particular build.
Therefore if the user specifies 'BB_NO_NETWORK = "1"', the _git versions of
the tpm2 recipes will cause the build to fail even if the _git versions are
not going to be built (which they won't be by default on account of their
DEFAULT_PREFERENCE being set to "-1").

This fix follows the same pattern as
https://github.com/sbabic/meta-swupdate/commit/721fcc89c53debcd6582bd1aa972f75297cf12e9

With this fix, the user can disable networking and successfully build the
non-_git versions of the tpm2 recipes. If the user wants to build the _git
versions, networking must be enabled. The build is expected to fail if the
user asks for the _git versions, but disables networking.
