[pkg-opensc-maint] Bug#884199: libp11 should provide a transitional package libengine-pkcs11-openssl1.1 for buster

[Adrian Bunk]

Source: libp11
Version: 0.4.7-2
Severity: normal

Currently users would end up with keeping libengine-pkcs11-openssl1.1
installed after a stretch -> buster upgrade.

Providing libengine-pkcs11-openssl1.1 as transitional package
depending on libengine-pkcs11-openssl (>= 0.4.7-2) would
upgrade them to the now 1.1-using libengine-pkcs11-openssl.
