Referencing libSupportHTTP under LINK_LIBS of add_lldb_library() pulls
in the static archive even in a build configuration with
LLVM_LINK_LLVM_DYLIB=On, where libSupportHTTP is part of libLLVM. This
patch moves it to LINK_COMPONENTS to fix the issue.
This is the same fix as in
036429881f8d3037894042c6268b2a94eac8c950, applied on another
library.
