linux-yocto-3.4: Disable extra slang header search path

Add in a workaround to avoid host infection detection build failures
from the slang include directory in perf. I'll defer to Bruce to
fix this properly but we need a workaround now as this is breaking
builds.

+We (OE) install slang into /usr/include so we never need to look into 
+/usr/include/slang/. We never want to look into a hardcoded path like this
+since it triggers host infection issues. For now, simply remove this
+since it causes us problems.

+Upstream-Status: Pending (would need rework)
