Resolve IndexOOBException in SigningDetails#hasAncestor
When a package that is part of a shareduid is installed / updated its
lineage is compared against the current signature / lineage for the
shareduid. If the new package has more than one signature in the lineage
an IndexOutOfBoundsException is thrown by SigningDetails#hasAncestor
crashing the system server. This commit ensures the ancestor check
is only performed against the current signer for the shareduid.
