plugins: Add multiboot select plugin

This plugin provides a menu for easily editing the root redirect file
on targets that support multiboot. You can select a new root from a
list of Rockbox installations detected on the filesystem or remove all
redirects to boot from the default location.

To avoid searching the whole filesystem, only subdirectories of the
volume roots are checked for valid installations. Only installations
that are compatible with the current player will be displayed.
