llvm36: fix code-signing certificate setup check (#1292)

The LLVM formula checks if the LLDB code signing certificate is set up
correctly by trying to sign an empty text file. On certain versions of
OS X, this causes codesign to segfault. This "fixes" it in a hackish way
by trying to sign an actual binary instead.
