check-exec: write file in 'wcache' instead of 'cache'
Some cache are relevant or affected by the working copy used. So the `.hg/cache`
directory is not the best place for them because multiple shared repository can
end up fighting over them.
To address this issue, we introduce a new 'wcache' directory to host this kind
of cache.
The first user are the `checkisexec` type file. These files describe property of
the working copy and fit the use-case well.
