Rust installed files reside in "$MODULE_OUT/stripped/" when they are stripped, otherwise they reside in "$MODULE_OUT". However, other parts of Soong assume that installed files are always in $MODULE_OUT (cc_modules place *unstripped* files in $MODULE_OUT/unstripped). This notably causes problems when adding Rust modules as test data in AndroidMkDataPaths. When Rust modules are parsed by AndroidMkDataPaths, if they are stripped then they incorrectly get installed as test data with the path: <install_root>/<relative_install_path>/stripped/file. This CL refactors how we handle Rust stripped output such that the installed file always resides in $MODULE_OUT. Bug: 171710847 Test: Installed files now always reside in $MODULE_OUT Change-Id: I53a6ff57a0a5a55cd95ea78ae592ce22abfa20c9
