Adam Williamson 5e72956199 Revert "Use my sort patch instead", fix BLS ostree detection
This reverts commit 93004a8494,
because it broke Rawhide. It also tries to fixes BLS ostree
detection to work in chroots (e.g. during installation) by also
checking for /ostree/repo.

Subject: [PATCH] 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)
