daemon: Change default ‘timeout’ and ‘max-silent-time’ values.

Having a timeout seems generally preferable as it makes sure build slots
are not kept busy for no good reason (few package builds, if any, are
expected to exceed these values).

* nix/libstore/globals.cc (Settings::Settings): Change ‘maxSilentTime’
and ‘buildTimeout’.
* gnu/services/base.scm (<guix-configuration>)[max-silent-time]
[timeout]: Change default values.
* doc/guix.texi (Invoking guix-daemon, Base Services): Adjust
accordingly.
