numactl: fix uclibc build issue

The patch added in commit 21ed7a92fe5a771911ef06f97522e504d0eebbc2 to
fix the musl build had the unfortunate consequence to break the build
on uClibc. Thanks to Bernd's work with upstream, both the musl and
uclibc issues have been fixed upstream, so this patch updates our
numactl package to use the two upstream commits instead of our own
private patch.
