test: move ignore test run into a subdirectory

Previously the hgignore test just called hg init in the test directory. A future
patch needs to test hgignore stuff from outside of the repo, so let's move the
entire test repo into a subdirectory.

  $ hg init
  $ mkdir a
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ hg ci -m m a

  $ mkdir a b
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ cd b

Relative delete:

  $ hg ci -m m ../a

  $ cd ..
