censor: make censor acquire locks before processing

Before this patch, "hg censor" executes below:

  - without acquisition of wlock, examine whether the working
    directory refers the revision of the file to be censored or not

  - without acquisition of store lock (slock), replace existing
    filelog of file to be censored with censored one,

    Replacement consists of steps below, and it is assumed that the
    destination filelog at (1) isn't changed before renaming at (3).

    1. read existing filelog in
    2. write filelog entries (both censored and not) into temporary file
    3. rename from temporary file to existing filelog to be censored

It may cause unintentional result, if another command runs parallelly
(see also issue4368).

This patch makes "hg censor" acquire wlock and slock before
processing.

Ensure debuild doesn't run the testsuite, as that could get silly.

We check debian package contents with portable tools so that when
we're on non-debian machines we can still test the packages that are
built using docker.

main deb should have .so but no .py
  $ ar x mercurial_*.deb
  $ tar tf data.tar* | egrep '(localrepo|parsers)'
  ./usr/lib/python2.7/dist-packages/mercurial/parsers*.so (glob)
mercurial-common should have .py but no .so or .pyc
  $ ar x mercurial-common_*.deb
  $ tar tf data.tar* | egrep '(localrepo|parsers)'
  ./usr/lib/python2.7/dist-packages/mercurial/localrepo.py
