[Buildroot] [PATCH v2 5/5] package/ti-sgx-km: use modules-load to load the kernel module

[unixmania at gmail.com <unixmania@gmail.com>]

From: Carlos Santos <unixmania@gmail.com>

This is compatible with BusyBox/sysvinit (via S02modules-load), OpenRC
and systemd. It also prevents trying to load the module each time the
init script is executed.

Remove the insmod command from the ti-sgx-um init script.

Tested on a BeagleBone Black card using beaglebone_qt5_defconfig.
