syscalls: 'define-as-needed' does not re-export local variables.
Fixes <https://bugs.gnu.org/36723>.
Reported by Timothy Sample <samplet@ngyro.com>.
* guix/build/syscalls.scm (define-as-needed): Rewrite to use lower-level
module primitives; define VARIABLE only if it's not already defined to
avoid "re-exporting local variable" error.
