utilities/ovs-ctl: Force removal of ip_gre/gre
On Linux kernels older than 4.16 the user cannot take advantage of
OVS ERSPAN features if the older ip_gre and gre kernel modules are
loaded. In addition, the openvswitch kernel module will fail to
load because it cannot grab the IPPROTO_GRE inet protocol handler
since the gre kernel module has already taken it.
Update the force_reload_kmod() script function to force removal
of the ip_gre and gre built-in kernel modules so that the openvswitch
kernel module can load and provide support for ERSPAN.
