[bug#60429] [PATCH v2 2/5] gnu: yosys: Use new package style.

[Simon South <simon@simonsouth.net>]

* gnu/packages/fpga.scm (yosys)[source]: Use gexp in snippet and don't
explicitly return #t.
[arguments]: Use gexps; use search-input-file to locate executables; simplify
parameters to "configure" phase; don't explicitly return #t from phases.
[native-inputs]: Sort alphabetically.
[inputs]: Sort alphabetically.
