Move 'tag=' for a few SRC_URIs to SRCREV

Sending in response to:

Building with BB_NO_NETWORK can fail if recipes specify 'tag=' in SRC_URI, since bitbake must contact the source repository to verify which hash the tag currently points to. Since tags can, in principle, change, current best practice is to omit 'tag=' from SRC_URIs and instead specify the required revision hash in SRCREV.

SHA hashes *cannot* change, so they should not need to be checked, in theory; however, bitbake currently has no mechanism for distinguishing between human-friendly tags like 'v2.1.2' and SHA-1 sums like 'fdb6c0402337d9607c7a39155088eaf033742752': both will result in a call to git ls-remote to verify the tag, which is problematic for BB_NO_NETWORK builds.

The second part of this patch was, I think, already submitted, but not yet applied to master[?]:
