test-tx-rollback: more lenient glob for kill status (issue6807)

The "killed" message may have some prefix and/or suffix which differ
depending on the platform.

This makes the pinned test output more lenient to accept those.

#testcases dirstate-v1 dirstate-v2

#if dirstate-v2
  $ cat >> $HGRCPATH << EOF
  > [format]
  > use-dirstate-v2=1
  > [storage]
  > dirstate-v2.slow-path=allow
  > EOF
#endif

Checking the size/permissions/file-type of files stored in the
dirstate after an update where the files are changed concurrently
outside of hg's control.

  $ hg init repo
  $ cd repo
  $ echo a > a
  $ hg commit -qAm _
  $ echo aa > a
  $ hg commit -m _
# this sleep is there to ensure current time has -at-least- one second away
# from the current time. It ensure the mtime is not ambiguous. If the test
# "sleep" longer this will be fine.
# It is not used to synchronise parallele operation so it is "fine" to use it.
  $ sleep 1
  $ hg status

  $ hg debugdirstate --no-dates
  n 644          3 (set  |unset)               a (re)

Do an update where file 'a' is changed between hg writing it to disk
and hg writing the dirstate. The dirstate is correct nonetheless, and
so hg status correctly shows a as clean.

  $ hg up -r 0 --config extensions.race=$TESTTMP/dirstaterace.py
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debugdirstate --no-dates
  n 644          2 (set  |unset)               a (re)
  $ echo a > a; hg status; hg diff

Do a commit where file 'a' is changed between hg committing its new
revision into the repository, and the writing of the dirstate.

This used to results in a corrupted dirstate (size did not match committed size).

  $ echo aaa > a; hg commit -qm _
  $ hg merge -qr 1; hg resolve -m; rm a.orig
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  (no more unresolved files)
  $ cat a
