vboot/secdata: rename rollback_index to secdata_tpm

These secure spaces are now used for more than just rollback
versions and should be renamed thus.

Note: Originally this rename operation was batched into the CL
which rewrites the functions in rollback_index/secdata_tpm, but
it made reviewing in Gerrit a pain, since it couldn't pick up on
the file renames, and instead showed them as deletes/adds.

Doing the rename separately helps ensure all references to
rollback_index are updated, and gives us a better review
experience in Gerrit.
