mako 15.1 jars do not appear to be signed

[rlbdv]

e.g. from https://download.lineage.microg.org/mako/

$ keytool -list -printcert -jarfile lineage-15.1-20180604-microG-mako.zip
Not a signed jar file

but the 14.1 image is signed:

$ keytool -list -printcert -jarfile lineage-14.1-20180427-microG-mako.zip
Signer #1:
...

But the 14.1 image there, https://download.lineage.microg.org/mako/lineage-14.1-20180427-microG-mako.zip is signed.

IMHO this should be reopened since the website has to be updated to explain how to verify the new signature format.

This seems to be tracked in #58 now.
