Subject: [PATCH 07/23] dl: provide a fake grub_dl_set_persistent for the emu
target
Trying to start grub-emu with a module that calls grub_dl_set_persistent
will crash because grub-emu fakes modules and passes NULL to the module
init function.
Provide an empty function for the emu case.
Fixes: ee7808e2197c (dl: Add support for persistent modules)
