doc: Factorize documentation of common build options.

* doc/guix.texi (Invoking guix package): Remove documentation for
  --dry-run, --fallback, --no-substitutes, and --max-silent-time.  Add a
  cross-ref to "Invoking guix build".
  (Invoking guix archive): Add "common build options" as the cross-ref
  topic for "Invoking guix build".
  (Invoking guix build): Move common build options separately.  Add a
  paragraph to explain.

When substituting a pre-built binary fails, fall back to building
packages locally.

Do not use substitutes for build products.  That is, always build things
locally instead of allowing downloads of pre-built binaries.

Produce verbose output.  In particular, emit the environment's build log
on the standard error port.
