largefiles: don't create chain of __contains__ calls

Matt Harbison pointed out that my recent 2720f967a7b1 might cause
__contains__ to continously get replaced by another version that calls
itself, since the manifest instance returned by the super method is
always the same instance due to @propertycache. He also suggested
replacing the class instead, as is done with the context class in the
surrounding code. Do so.

#!/usr/bin/env python

import sys
import os

os.chdir(os.getenv('TESTTMP'))

if sys.argv[1] != "user@dummy":
    sys.exit(-1)

os.environ["SSH_CLIENT"] = "127.0.0.1 1 2"

log = open("dummylog", "ab")
log.write("Got arguments")
for i, arg in enumerate(sys.argv[1:]):
    log.write(" %d:%s" % (i + 1, arg))
log.write("\n")
log.close()
hgcmd = sys.argv[2]
if os.name == 'nt':
    # hack to make simple unix single quote quoting work on windows
    hgcmd = hgcmd.replace("'", '"')
r = os.system(hgcmd)
sys.exit(bool(r))
