package/libcap: disable GOLANG

Recently, the go infrastructure has changed, and libcap has been
upgraded to 2.42. libcap introduced golang in 2.28, see:

https://git.kernel.org/pub/scm/linux/kernel/git/morgan/libcap.git/commit/Make.Rules?id=0615d996379dceedefcd65a114f93fefd81c208f

When you compile host-go and then compile host-libcap, GOLANG will be
automatically set to yes. Because libcap.mk lacks golang support,
compilation will fail.
