tests/assert-install.sh: Always to enforce correct installation

Also in this change:

- now we call ln(1) in the "install" target without using the -r
  "relative" flag, as it isn't POSIX;
- add `+` as a prefix to the "assert-tests" command, so we tell sub-make
  calls to also run things in parallel.  In this case, the
  "make DESTDIR=... install" calls;
- use the implicit `index.js` entrypoint and do away completly with
  `package.json`;
- change from `import` to `require` as Node.js ESM modules don't support
  `$NODE_PATH`[0]: "NODE_PATH is not part of resolving import
  specifiers. Please use symlinks if this behavior is desired." 🤦;

The parallel sub-make behaviour isn't available in current specification
of make (POSIX issue 7) but is included in the upcoming[1] version 8:

> If a rule invokes a sub-make either via the MAKE macro or via a
> command line that begins with '+', the sub-make is the same
> implementation as the make that invoked the sub-make, and the −j
> option is passed to the sub-make via the MAKEFLAGS environment
> variable with the same maxjobs value and is not overridden by a
> maxjobs value from another source (even if it has the same value), the
> sub-make shall use the same token pool as its invoking make rather
> than create a new token pool.
