[ Upstream commit 3f3f384139ed147c71e1d770accf610133d5309b ]
When kselftest is built/installed with the 'gen_tar' target, rsync is used for the installation step to copy files. Extra care is needed for tests that have symlinks. Commit ae108c48b5d2 ("selftests: net: Fix cross-tree inclusion of scripts") added '-L' (transform symlink into referent file/dir) to rsync, to fix dangling links. However, that broke some tests where the symlink (being a symlink) is part of the test (e.g. exec:execveat).
Use rsync's '--copy-unsafe-links' that does right thing.
