Drop patch fixing a corner case in BLS variable expansion

There is a bug reported about a system failing to boot with the latest pkg
and the only relevant change was this patch. Drop it just to be sure since
it is fixing a corner case in variable expansion so is not worth the risk.

-Subject: [PATCH] blscfg: add a space char when appending fields for variable
- expansion
-
-The GRUB variables are expanded and replaced by their values before adding
-menu entries, but they didn't include space characters after the values so
-the result was not correct.
-
-For the common case this wasn't a problem but it is if there are variables
-that are part of the values of other variables.
