Documentation: Fix kernel support matrix

The documentation matrix for OVS branches and which kernels they support
is out of date.  Update it to show that since 2.10 the lowest kernel
that we test and support is Linux 3.16.

RHEL and CentOS kernels based upon the original 3.10 kernel are still
supported.

     Open vSwitch userspace is not sensitive to the Linux kernel version.  It
     should build against almost any kernel, certainly against 2.6.32 and later.

 Q: Are all features available with all datapaths?
 
     A: Open vSwitch supports different datapaths on different platforms.  Each
