Remove working directory for debugserver code signing target

[lanza]

Summary

LLVM puts output binaries in
${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/bin. This chunk of
code left out the ${CMAKE_CFG_INTDIR}. Ultimately, the code signing target
does not need a working directory anyways, so it's safe to just remove it.

Honestly, I don't know that we need to specify a working directory on this command at all. Since we're specifying the target file using a generator expression everything else should work because we use explicit not relative paths.

Good point, updated accordingly.
