Rather than relying on carefully avoiding touching the 9P-mounted
/nix/store, we instead install a small NixOS system, similar to
the installer tests, and boot from that.
This avoids the various pitfalls associated with trying to unsuspend
properly and trades off a bunch of boilerplate for what will hopefully
be a more reliable test.
Additionally, this test now actually tests booting the system using a
bootloader, rather than the previous method of just booting the kernel
directly.
Tested building pkgsCross.x86_64-netbsd.netbsd.libm from x86_64-linux.
At some point we should probably set SHLIBINSTALLDIR in the setupHook,
but I think I'd like to get everything working first, and then make
changes that affect all the builds like that. It's easier to spot
regressions when you know _everything_ worked before.
Previously unstable versions would not have been found, because the
regular expression was looking for a numeric version after the attribute
name. When the version is however an unstable one, it would start with
> unstable-2021-04-23
and therefore not match the pattern.
There is just one test failure on darwin, and it can probably be worked
around by allowing local networking.
This should hopefully fix the following testsuite error:
```

- No splicing makes everything less finnicky.
- Normal bootstrapping matches e.g. linux where kernel headers are also
`stdenvNoCC` but part of this stage.
