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.
For #74466
Fixes #74892
