The LC_SUB_FRAMEWORK, LC_SUB_UMBRELLA, LC_SUB_CLIENT, and LC_SUB_LIBRARY are used to indicate related libraries, binaries or framework names. Their only payload is the string with the name of the object. Adding those commands to the list of ignored/skipped load commands will avoid an error that stop the process of copying/stripping and will copy their contents verbatim. Additionally, in order to have a test for this case, `yaml2obj` now allows those four commands to contain a `Content`. Differential Revision: https://reviews.llvm.org/D106412
