From d7a0fc190b00fbb083688993971f466df834ceaa Mon Sep 17 00:00:00 2001

Subject: [PATCH] lib/, bin/: fix signature type, now called *.sig2
Since 8d5c48b, xbps has used a sha1 ASN1 prefix with a sha256 hash, and
as of openssl v3, openssl cares about this. This works around that in a
compatible way by moving to a second sig file, binpkg.sig2.
For xbps-remove -O and xbps-rindex -r, also clean up obselete .sig files.
