core: set dumpable flag after setuid

When ceph-* drops drops privileges via setuid, core dumps are no longer
generated because its DUMPABLE flag is cleared. We have to manually
turn that back on.

From prctl(2):

      Normally, this flag is set to 1.  However, it is reset to the current value contained in the file /proc/sys/fs/suid_dumpable (which by default has the value 0), in the fol‐
      lowing circumstances:

      *  The process's effective user or group ID is changed.

      *  The process's filesystem user or group ID is changed (see credentials(7)).

      *  The process executes (execve(2)) a set-user-ID or set-group-ID program, or a program that has capabilities (see capabilities(7)).

ceph-disk: allow using a regular file as a journal

Because of a missing return, ceph-disk prepare would fail if given a
regular file as a journal. If the journal file does not exist, ceph-disk
will create it but fail to ensure that the ceph user owns it. The
symlink to the journal file is not set when the journal file is
specified on the command line and the journal file does not exist at
all. The ceph-osd daemon will silently create it as a file but it will
not be the file given in argument.

Add a test case to verify using a regular file as a journal works as
expected.
