Lock patchless profile to el7.6
Since we reference 7.6 in zfs repo, we shouldn't try to install
on any other rev-level
"validation": [
{
"description": "The profile is designed for version 7 of EL",
- "test": "distro_version < 8 and distro_version >= 7"
+ "test": "distro_version < 7.7 and distro_version > 7.5"
}
]
}
