backtrace because code expects 'read-boot-parameters' to always return a
&lt;boot-parameters&gt; record.

* gnu/system.scm (read-boot-parameters): Upon incompatibility, raise an
error instead of returning #f.  Also raise a '&amp;fix-hint' condition.
* tests/boot-parameters.scm ("read, construction, mandatory fields"):
Define 'test-read-boot-parameters' as a macro; expect
'formatted-message?' exceptions rather than #f returns.
