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.

  $ hg init
  $ touch a

  $ unset HGUSER
  $ echo "[ui]" >> .hg/hgrc
  $ echo "username= foo" >> .hg/hgrc
  $ echo "          bar1" >> .hg/hgrc

  $ hg ci -Am m
  adding a
  abort: username 'foo\nbar1' contains a newline
  
  [255]
  $ rm .hg/hgrc

  $ HGUSER=`(echo foo; echo bar2)` hg ci -Am m
  adding a
  abort: username 'foo\nbar2' contains a newline
  
  [255]
  $ hg ci -Am m -u "`(echo foo; echo bar3)`"
  adding a
  transaction abort!
  rollback completed
  abort: username 'foo\nbar3' contains a newline!
