discover/grub2: Do not set $0 in functions
GRUB2 does not set $0 in functions, so don't set it in our GRUB2
script parser. (As it doesn't have a value in GRUB2 scripts, probably
no GRUB2 script depends on the value of $0.) Additionally, dash and
bash set environment variable 0 to the name of the script (even in
functions), so the current behavior of $0 doesn't really match shell
scripts either.
Tested:
Existing tests pass.
