Subject: Fix grub-zfs-snap command substitution syntax error

Remove backslash escape from grub-probe command substitution so it
executes at config generation time instead of writing the literal
string "$(grub-probe ...)" into grub.cfg.

GRUB's scripting language doesn't support bash-style $() command
substitution, causing syntax errors on boot.
