init/Kconfig: Add option to set modprobe command
The hard-coded path of modprobe doesn't allow distros to put the binary
in another place without add links from one place to another. For
example, in recent versions of distros like Fedora, Arch and Suse, kmod
is the default tool to load modules and they have to create a link from
modprobe to kmod binary. kmod relies on argv[0] to know what to do but
in future they want to add commands like "kmod load -- modulename",
which is not possible if the path to the tool to load modules is
hard-coded in kernel.
Moreover, it's already possible to set the path through /proc/sys, but
it would have to be done very early in the boot sequence and on every
boot since modprobe may be called even before / is mounted. In this
scenario booting without and initrd would be more difficult as well.
