Fix: OS name detection error by build scripts

There is a problem detecting OS specific scripts dir if NAME variable in
/etc/os-release contains a multi-word string (e.g NAME="CentOS Linux").
To fix this we get first part of the NAME string (i.e "CentOS") for
simplicity and look for version specific scripts dir within that.
