remove pointless os.path.join calls when opening files in .hg/cache

Windows deals just fine with '/' in paths and Mercurial on Windows
already does file accesses elsewhere with mixed \ and / in file
paths anyway.

This patch also makes the static-http repo case use proper URLs of the
form

  http://example.com/repo/.hg/cache/branchheads
  http://example.com/repo/.hg/cache/tags

instead of the entirely pointless

  http://example.com/repo/.hg/cache%5Cbranchheads
  http://example.com/repo/.hg/cache%5tags

(as introduced by 5ccdca7df211)
