Subject: emulation: Limit integer arguments to 65535

To guard against malicious sequences containing excessively big numbers,
limit all parsed numbers to 16 bit range. Doing this here in the parsing
routine is a catch-all guard; this doesn't preclude enforcing
more stringent limits in the handlers themselves.

effect: first because ‘guix time-machine --commit=X’, not followed by a
command, does nothing, and second because the “! COMMAND” shell stanza
does not have the desired effect (see &lt;https://issues.guix.gnu.org/62406&gt;).

This change rewrites the test to make it effective.

* tests/guix-time-machine.sh: Rewrite.
