largefiles: invoke "normallookup" on "lfdirstate" for merged files

Before this patch, largefiles gotten from "other" revision (with
conflict) at "hg merge" become "clean" unexpectedly in steps below:

    1. "repo.status()" is invoked (for status check before merging)
      1-1 "dirstate" entry for standinfile SF is "normal"-ed
      1-2 "lfdirstate" entry of largefile LF (for SF) is "normal"-ed

    2. "merge.update()" is invoked
      2-1 SF is updated in the working directory
          (ASSUMPTION: user choice "other" at conflict)
      2-2 "dirstate" entry for SF is "merge"-ed

    3. "lfcommands.updatelfiles()" is invoked (by "overrides.hgmerge()")
      3-1 largefile LF (for SF) is updated in the working directory
      3-2 "dirstate" returns "m" for SF (by 2-2)
      3-3 "lfdirstate" entry for LF is left as it is
      3-4 "lfdirstate" is written into ".hg/largefiles/dirstate", and
          timestamp of LF is stored into "lfdirstate" file (by 1-2)
          (ASSUMPTION: timestamp of LF differs from one of "lfdirstate" file)

Then, "hs status" treats LF as "clean", even though LF is updated by
"other" revision (by 3-1), because "lfilesrepo.status()" always treats
"normal"-ed files (by 1-2 and 3-4) as "clean".

When state of standinfile in "dirstate" is "m", largefile should be
"normallookup"-ed.

This patch invokes "normallookup" on "lfdirstate" for merged files.

This patch uses "[debug] dirstate.delaywrite" feature in the test, to
ensure that timestamp of the largefile gotten from "other" revision is
stored into ".hg/largefiles/dirstate". (for ASSUMPTION at 3-4)
