Subject: gnu: guile-gcrypt: Refer to the right libgcrypt when cross-compiling.

Fixes a regression introduced in
5e163ba00969e7ba05897840a1199b967252b4ae where (gcrypt package-config)
would end up referring to the native libgcrypt.so instead of the target
one.

* gnu/packages/gnupg.scm (guile-gcrypt)[arguments]: Reintroduce
'add-libgrypt-config' phase.
[native-inputs]: Remove LIBGCRYPT.
