Seewer mentioned that instmods =block is failing to pull in block device

Under the assumption that we cannot rely on modules.* list files since
it is not shipped by other distributions, the next best thing is to do a
similar scanning during dracut runtime. This is a bit slower than
simply reading the modules.* files but it seems we have no choice.
I had implemented the equivalent of "modesetting" and the important
subset of "networking" that we require in dracut. The equivalent for
"block" however is a bit more complex given the long list of alternative
symbol names.
I had considered implementing the equivalent of collect_modules_list in
dracut. Perhaps we could implement the equivalent with an additional
parameter of base directory so it does not bother scanning the entire
directory tree looking for modules.
Just a thought.
All I can say here is yes please!
