hgweb: overwrite cwd to resolve file patterns relative to repo (issue4568)

It's useless to handle file patterns as relative to the cwd of the server
process. The only sensible way in hgweb is to resolve paths relative to the
repository root.

It seems dirstate.getcwd() isn't used to get a real file path, so this patch
won't cause problem.

  $ mkdir -p t
  $ cd t
  $ cat <<EOF > merge
  > import sys, os
  > f = open(sys.argv[1], "wb")
  > f.write("merge %s %s %s" % (sys.argv[1], sys.argv[2], sys.argv[3]))
  > f.close()
  > EOF

perform a test merge with possible renaming
args:
$1 = action in local branch
$2 = action in remote branch
$3 = action in working dir
$4 = expected result
