Dmitri Shuralyov ea96074191 [release-branch.go1.22] os/exec: only use cachedLookExtensions if Cmd.Path is unmodified 
Caching the invocation of lookExtensions on an absolute path in Command
and reusing the cached result in Start is only viable if Cmd.Path isn't
set to a different value after Command returns.

For #66586.
For #68314.
Fixes #68331.
