[Buildroot] [PATCH 1/1] package/znc: set WANT_SWIG

[Fabrice Fontaine]

Set WANT_SWIG={ON,OFF} to {en,dis}able swig and avoid a random build
failures probably due to parallel build issue when extracting
pre-generated tarball:

CMake Error: Problem with archive_write_header(): Can't unlink already-existing object
CMake Error: Current file: swigpyrun.h
CMake Error: Problem extracting tar: /usr/lfs/hdd_v1/rc-buildroot-test/scripts/instance-0/output/build/znc-1.7.5/modules/modpython/generated.tar.gz

Fixes:
