Remove the lldb-core level User Header Search Paths from the Release configuration.
Remove the lldb-core level User Header Search Paths from the Release configuration.

This was probably introduced by a merge.  The lldb-core target had search paths at
the target level for the Release configuration that were clearly from llvm.org.  They
lacked all the swift includes.  That meant the Release configuration build failed
when it touched the first swift include.
