branchcache: stay silent if failing to read cache files

The warning has in some cases incorrectly attributed unrelated problems to rbc.

Instead, just do like the branch head cache does and stay quiet when reading
fails. The cache will be missing the first time a repo is used. It is a normal
situation and there is no reason to make a note of that.

     rbc-names is append-only, and each branch name is only stored once and will

     The branch info for each revision is stored in rbc-revs as constant size
     records. The whole file is read into memory, but it is only 'parsed' on
     demand. The file is usually append-only but will be truncated if repo
     modification is detected.
     The record for each revision contains the first 4 bytes of the
     corresponding node hash, and the record is only used if it still matches.
     Even a completely trashed rbc-revs fill thus still give the right result
     while converging towards full recovery ... assuming no incorrectly matching
     node hashes.
     The record also contains 4 bytes where 31 bits contains the index of the
     branch and the last bit indicate that it is a branch close commit.
