[kernel] copy modprobe.d/*.conf from other possible locations

There might be module configuration files (modprobe.d/*.conf)
not only in /etc, but also in /lib, /run, and /usr/local/lib,
per modprobe.d(5) [1].

Let's copy those too.

P.S.: /lib is correct for distros with distinct /usr/lib too
(checked on Ubuntu 14.04/16.04/18.04 and 20.04/22.04).

[1] https://git.kernel.org/pub/scm/utils/kernel/kmod/kmod.git/tree/man/
    modprobe.d.xml?h=v30#n42

Test steps:

    $ for dir in /etc /lib /run /usr/local/lib
    do
      dir=$dir/modprobe.d
      sudo mkdir -p $dir
      sudo touch $dir/test.conf
    done

    $ sudo ./bin/sos report -o kernel --batch --quiet
    $ sudo tar tf /tmp/sosreport-*.tar.xz \
        | grep -o '/.*/modprobe.d/test.conf'
    $ sudo rm -f /tmp/sosreport-*

    $ for dir in /etc /lib /run /usr/local/lib
    do
      sudo rm -f $dir/modprobe.d/test.conf
    done

Before:

    $ sudo tar tf /tmp/sosreport-*.tar.xz \
        | grep -o '/.*/modprobe.d/test.conf'
    /etc/modprobe.d/test.conf

After:

    $ sudo tar tf /tmp/sosreport-*.tar.xz \
        | grep -o '/.*/modprobe.d/test.conf'
    /etc/modprobe.d/test.conf
    /run/modprobe.d/test.conf
    /usr/lib/modprobe.d/test.conf
    /usr/local/lib/modprobe.d/test.conf
