[release-branch.go1.24] os/exec: fix incorrect expansion of ".." in LookPath on plan9 The correction in CL 685755 is incomplete for plan9, where path search is performed even on file strings containing "/". By applying filepath.Clean to the argument of validateLookPath, we can check for bogus file strings containing ".." where the later call to filepath.Join would transform a path like "badfile/dir/.." to "badfile" even where "dir" isn't a directory or doesn't exist.
