filemerge: make capability check for internal tools ignore merge-tools section

This is follow up of 4d7b11877dd0.

Before this patch, capability check of internal merge tools falls back
to _toolbool(), which examines configurations in "merge-tools" section.

But "hg help config" explicitly says that "merge-tools" section
configures external merge tools.

Therefore, this patch makes capability check for internal tools in
hascapability() always ignore configurations in merge-tools section.

In this patch, command line configurations below are added at tests in
tests/test-merge-tools.t, in order to confirm that explicit
configuration is intentionally ignored at tool selection.

  --config merge-tools.:INTERNAL_TOOL.CAPABILITY=true

  $ hg init
  $ echo a > a
  $ hg ci -Am0
  adding a

  $ hg -q clone . foo

  $ touch .hg/store/journal

  $ echo foo > a
  $ hg ci -Am0

  (run 'hg recover' to clean up transaction)

Check that zero-size journals are correctly aborted:

#if unix-permissions no-root
  $ hg bundle -qa repo.hg
  $ chmod -w foo/.hg/store/00changelog.i

  $ hg -R foo unbundle repo.hg

  abort: Permission denied: $TESTTMP/foo/.hg/store/.00changelog.i-* (glob)

  $ if test -f foo/.hg/store/journal; then echo 'journal exists :-('; fi
