fix more Forth-assembly words

the words that needed fixes were unroll, stringlen, 0branch, and sys-exit

this is now everything that's expected to agree, we're pretty sure

the disassemblies of litpack* contain absolute addresses of the corresponding pack* words, so those are expected to be different, and the differences look correct at the byte level

similarly, the implementation of docol is significantly different structurally and that's also expected

Force-Push: yes
