derivations: Optimize `write-derivation'.
This reduces the execution time of
"guix build -e '(@ (gnu packages emacs) emacs)' -d" by 25%, from
1.54 s. to 1.15s.
* guix/derivations.scm (write-sequence, write-list, write-tuple): New
procedures.
(write-derivation)[list->string, write-list]: Remove.
[write-string-list, write-output, write-input, write-env-var]: New helpers.
Rewrite in terms of these new helpers.
