[Pkg-auth-maintainers] Bug#900771: yubikey-ksm: depends on php-mcrypt which is no longer available in php7.2

[Emilio Pozuelo Monfort]

Package: yubikey-ksm
Version: 1.15-6
Severity: serious
Tags: sid buster

Your package depends on php-mcrypt, which is no longer provided since php7.2.
Since we are removing php versions older than that for buster, you should
update your package to no longer require that module.
