[bug#68048] [PATCH v2] gnu: cdparanoia: Fix cross-compiling.

[Zheng Junjie]

* gnu/packages/cdrom.scm (cdparanoia)
[native-inputs]: when cross compiling to {riscv,aarch}64-linux-gnu, add config.
[arguments]: when target {riscv,aarch}64-linux-gnu, add update-config-scripts 
phase.
<#:configure-flags>: when cross-compiling, use `(assoc-ref %outputs "out")'.
