Remove "guile-zlib" extension when unused.
This is a follow-up of 755f365b02.

As (zlib) is autoloaded in (gnu build linux-modules), "guile-zlib" is needed
as an extension only when it is effectively used.

* gnu/installer.scm (installer-program): Remove "guile-zlib" from the extensions.

linux-libre: Support module compression.
This commit adds support for GZIP compression for linux-libre kernel
modules. The initrd modules are kept uncompressed as the initrd is already
compressed as a whole.

The linux-libre kernel also supports XZ compression, but as Guix does not have
any available bindings for now, and the compression time is far more
significant, GZIP seems to be a better option.

* gnu/build/linux-modules.scm (modinfo-section-contents): Use
'call-with-gzip-input-port' to read from a module file using '.gz' extension,

uncompressed module files.

services: 'fold-services' memoizes service values.
Previously 'fold-services' could end up traversing the same services in
the graph several times, which is what this change addresses.

The hit rate on the 'add-data-to-store' cache goves from 9% to 8% on
"guix system build desktop.tmpl -nd", and the number of lookups in that
cache goes from 4458 to 4383.

services: Export 'service-extension' procedures.
* gnu/services.scm: Export service-extension-target and
service-extension-compute.  This allows for greater extensiblity of services
by enabling service extensions to be wrapped.  For example, the parameters
passed to the compute function can be modified, or the return value of the
compute function can be modified.
