nongnu: winetricks: Improve package style.

* nongnu/packages/wine.scm (winetricks)[inputs]: Use label-less style.
[arguments]: Use G-expressions.
<#:make-flags>: Replace '(assoc-ref %outputs "out")' with '#$output'.
<#:phases>: In 'wrap-program' and 'patch-perl-path', Replace
'(assoc-ref inputs ...)' with 'this-package-input'.
