run-tests: don't append rtendtracing logs if pipe is /dev/null

If HGCATAPULTSERVERPIPE is not set, we set it to /dev/null, so we need to make
sure the value is not /dev/null before appending logs.

This fixes some of test-run-tests.t failures.

rebase with multiple root.
We rebase E and G on B
We would expect heads are I, F if it was supported

  $ hg clone -q -u . ah ah6
  $ cd ah6
  $ hg rebase -r '(4+6)::' -d 1
  rebasing 4:c01897464e7f "E"

More complex rebase with multiple roots
each root have a different common ancestor with the destination and this is a detach

(setup)

  $ hg clone -q -u . a a8
  $ cd a8
  $ echo I > I
  $ hg add I
  $ hg commit -m I
  $ hg up 4
  1 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ echo I > J
  $ hg add J
  $ hg commit -m J
  created new head
  $ echo I > K
  $ hg add K
  $ hg commit -m K

Test that rebase is not confused by $CWD disappearing during rebase (issue4121)

  $ hg commit -m 'first source commit'

  $ cd subdir

  $ hg add subfile
  $ hg commit -m 'second source with subdir'

  $ hg rebase -b . -d 1 --traceback

Get back to the root of cwd-vanish. Note that even though `cd ..`
works on most systems, it does not work on FreeBSD 10, so we use an
absolute path to get back to the repository.
