Rust subprojects have the semantic version (followed by -rs) in the subproject
name, but the full version (without -rs) is used by crates.io for the root
directory of the tarball.  Teach scripts/archive-source.sh to look for the
root directory name in wrap files.

v1->v2:
- put local dir on separate line
- use :- to print default even if $dir is empty
- use error function and invert "if test -f" condition
- simplify sed script to avoid jumps
