packages: Factorize and document 'computed-origin-method'.
The 'computed-origin-method' had been introduced to work around
limitations of the 'snippet' mechanism. The procedure was duplicated,
which made it hard to automatically detect packages using it.
* guix/packages.scm (computed-origin-method): Move procedure from...
* gnu/packages/gnuzilla.scm: ...here and...
* gnu/packages/gnuzilla.scm: ...there.
