Subject: [PATCH] More reliable way to determine package manager type during
 the build

Checking presence of 'apt', 'yum' or 'zypper' command is not very
reliable way to determine package manager type.
E.g. OpenSUSE 25 has 'apt' which is wrapper over 'zypper' or rpm tools
can be installed on Ubuntu.
More relible way is to check /etc/*-release file and if it is not
availabe try to check presence of apt, yum or zypper
