discover/grub2: Fix handling of positional parameters
Positional parameters are set in the environment with '$' prepended to
the name. This causes lookups to fail because parameter lookups don't
include the '$'.
TESTED:
Added a test that covers positional parameters in GRUB2 parser.
Build succeeds, tests pass.
