spec: Require newer kernel version on el7

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-3.10.0-295.el7. In this version, setting
session recovery_tmo using sysfs overrides the default value defined in
iscsid configuration file. We require now this kernel version.

The same issue probably exists in Fedora. We will need a second patch
to require the correct kernel version when we know which version is
needed.
