Dexoptanalyzer is getting a new mode to instruct installd on which dex files it needs to open for itself and dex2oat from class loader context. The file list is communicated by a pipe from a forked dexoptanalyzer process to the installd parent. Give dexoptanalyzer permission to write to installd's pipes.
