manifestdict: extract condition for _intersectfiles() and use for walk()

The condition on which manifestdict.matches() and manifestdict.walk()
take the fast path of iterating over files instead of the manifest, is
slightly different. Specifically, walk() does not take the fast path
for exact matchers and it does not avoid taking the fast path when
there are more than 100 files. Let's extract the condition so we don't
have to maintain it in two places and so walk() can gain these two
missing pieces of the condition (although there seems to be no current
caller of walk() with an exact matcher).

  $ hgcommit() {

  $ hg init clhead

  $ touch foo && hg add && hgcommit -m 'foo'
  adding foo

  adding bar
  $ touch baz && hg add && hgcommit -m 'baz'
  adding baz

close one of the heads
