Fix CentOS 7.6 detection

The version information in /etc/centos-release has 3 parts,
in particular for CentOS 7.6:

CentOS Linux release 7.6.1810 (Core)

This was misidentified as CentOS 6 because the substring "6."
was matched before matching "7.". This change fixes this by
requiring a space before the major version.
