gnu: nss-certs: Avoid top-level reference to NSS.

This is the only hammer I know for dealing with module cycles and
effectively fixes, for example, ‘guix show nss’ today.

It's also a very poor solution.

* gnu/packages/certs.scm (nss-certs)[version, source]: Copy verbatim
from the nss package rather than referring to it at the top level.

Reported by several users of #guix.

This fixes a crash when launching xdot.

* gnu/packages/graphviz.scm (xdot)[inputs]: Add harfbuzz.
[arguments]: Add harfbuzz to the GI_TYPELIB_PATH wrapper in the 'wrap' phase.

offload: Autoload Guile-SSH.

This halves the number of syscalls made by "guix offload" during startup
and delays loading of Guile-SSH until there are actually machines to
offload to.

modules.

'read-derivation-from-file', moved from...
(guix-offload): ... here.
