guix/tests/guix-time-machine.sh, branch master

tests: guix-time-machine: Actually fail if test fails.

2026-07-01T08:50:04+00:00

* tests/guix-time-machine.sh: Change "&& echo false" to "&& false"

tests: guix-time-machine: explicitly configure zero trusted channels.

2026-06-30T08:57:49+00:00

(current-channels) is empty in a regular guix checkout, but 'guix build guix'
passes --with-channel-commit=..., which causes it to return the configured
guix channel.  Consequently (trusted-channels) isn't empty and these tests
fail in 'guix build guix'.

* tests/guix-time-machine.sh: explicitly create an empty trusted-channels.scm.
