[Buildroot] [PATCH v2 4/5] package/owfs: 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.

Signed-off-by: Carlos Santos <unixmania@gmail.com>

Tested on QEMU with a kernel config with FUSE_FS=m. Only the module
loading was tested, since there is no 1-wire device.
