uvol: unbreak build and adapt to updated ucode
* Fix build which was broken by a wrong path in the Makefile.
Adapt to ucode commit 4618807 ("main: rework CLI frontend"):
* ucode now no longer needs the {% %} around each code file, remove
that and safe one level of indentation.
* ARGV now no longer includes ucode executable and script itself
Fixes: 6350c7bc6 ("uvol: replace with re-write in ucode")
