fsmonitor: only access inner dirstate map if it is available

As part of the dirstate refactor, fsmonitor was updated to directly access the
inner map of the dirstatemap object.

Dirstatemap reimplementations may not use a map like this, so only access it if
it is there.

Test template output

  1
  == ../c (c) == (glob)
  3

Environment variables are not visible by default

  $ PATTERN='t4' hg log -r '.' -T "{ifcontains('PATTERN', envvars, 'yes', 'no')}\n"
  no

Environment variable visibility can be explicit

  $ PATTERN='t4' hg log -r '.' -T "{envvars % '{key} -> {value}\n'}" \
  >                 --config "experimental.exportableenviron=PATTERN"
  PATTERN -> t4

Test behavior of output when directory structure does not already exist

  $ mkdir foo
  $ echo a > foo/a
  $ hg add foo/a
  $ hg commit -qm "add foo/a"
  $ hg cat --output "output/%p" foo/a
  $ cat output/foo/a
  a
