tests: disable infinitepush tests for simple store

Infinitepush relies heavily on bundles and bundlerepo. As such,
it won't be easy to make compatible with alternate storage
backends at this time.

Let's disable the tests when running with our simple store.

Differential Revision: https://phab.mercurial-scm.org/D3062

Setup:
  $ cat > eval.py <<EOF
  > from __future__ import absolute_import
  > import filecmp
  > from mercurial import commands, context, pycompat, registrar
  > cmdtable = {}
  > command = registrar.command(cmdtable)
  > @command(b'eval', [], b'hg eval CMD')
  > def eval_(ui, repo, *cmds, **opts):
  >     cmd = b" ".join(cmds)
  >     res = pycompat.bytestr(eval(cmd, globals(), locals()))
  >     ui.warn(b"%s" % res)
  > EOF

Arbitraryfilectx.cmp does not follow symlinks:
  $ mkdir case1
  $ cd case1
  $ hg init
#if symlink
  $ printf "A" > real_A
  $ printf "foo" > A
  $ printf "foo" > B
  $ ln -s A sym_A
  $ hg add .
  adding A
  adding B
  adding real_A
  adding sym_A
  $ hg commit -m "base"
#else
  $ hg import -q --bypass - <<EOF

These files are different and should return True (different):
(Note that filecmp.cmp's return semantics are inverted from ours, so we invert
for simplicity):
  $ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['real_A'])"
  True (no-eol)
  $ hg eval "not filecmp.cmp('A', 'real_A')"
  True (no-eol)

These files are identical and should return False (same):
  $ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['A'])"
  False (no-eol)
  $ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['B'])"
  False (no-eol)
  $ hg eval "not filecmp.cmp('A', 'B')"
  False (no-eol)

This comparison should also return False, since A and sym_A are substantially
the same in the eyes of ``filectx.cmp``, which looks at data only.
  $ hg eval "context.arbitraryfilectx('real_A', repo).cmp(repo[None]['sym_A'])"
  False (no-eol)

A naive use of filecmp on those two would wrongly return True, since it follows
the symlink to "A", which has different contents.
#if symlink
  $ hg eval "not filecmp.cmp('real_A', 'sym_A')"
  True (no-eol)
#else
  $ hg eval "not filecmp.cmp('real_A', 'sym_A')"
  False (no-eol)
#endif
