gexp: computed-file: Prevent mistakenly overriding default option values.
In order to do so, default to an empty options list, and expose options whose
default values are sensitive directly as keyword arguments.
* guix/gexp.scm (computed-file): Extract the LOCAL-BUILD? parameter from the
OPTIONS parameter to make it a stand-alone keyword argument. Introduce an
OPTIONS* binding which is obtained by combining the LOCAL-BUILD? keyword and
its value with OPTIONS.
* doc/guix.texi (G-Expressions): Adjust doc.
