spec: Require newer kernel version on EL

iSCSI default replacement_timeout is 120 seconds, resulting in too slow
iSCSI failover in multipath setup. In vdsm, this may lead to blocking of
multiple unrelated vdsm threads for many minutes, when lvm, multipath
ore scsi scan operation blocks.

This issue was resolved in multipath (BZ1099932), by configuring iscsi
session recovery_tmo sysfs attribute to multipath fast_io_fail_tmo
value, (5 seconds in vdsm configuration). However, this configuration
was reverted to the default 120 seconds after a device went down an up
again, or after restart of the iscsid daemon (BZ1139038).

This issue was fixed in kernel 3.10.0-229.17.1.el7. In this version,
setting session recovery_tmo using sysfs overrides the default value
defined in iscsid configuration file.
