rebase: suppress warning thrown when aborting rebase in case of dryrun

Before this patch dryrun output contained "rebase aborted" every
time we run rebase in dryrun mode and this warning does not sound
safe from a user prespective.

Rebase a simple DAG:
  $ hg init repo1
  $ cd repo1
  $ hg debugdrawdag <<'EOS'
  > c b
  > |/
  > d
  > |
  > a
  > EOS
  $ hg up -C a
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg tglog
  o  3: 814f6bd05178 'c'
  |
  | o  2: db0e82a16a62 'b'
  |/
  o  1: 02952614a83d 'd'
  |
  @  0: b173517d0057 'a'
  
  $ hg cat -r 3 c
  c (no-eol)
  $ hg cat -r 2 b
  b (no-eol)
  $ hg rebase --debug -r b -d c | grep rebasing
  rebasing in-memory
  rebasing 2:db0e82a16a62 "b" (b)
  $ hg tglog
  o  3: ca58782ad1e4 'b'
  |
  o  2: 814f6bd05178 'c'
  |
  o  1: 02952614a83d 'd'
  |
  @  0: b173517d0057 'a'
  
  $ hg cat -r 3 b
  b (no-eol)
  $ hg cat -r 2 c
  c (no-eol)

Case 2:
  $ hg init repo2
  $ cd repo2
  $ hg debugdrawdag <<'EOS'
  > c b
  > |/
  > d
  > |
  > a
  > EOS

Add a symlink and executable file:
  $ hg up -C c
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ ln -s somefile e
  $ echo f > f
  $ chmod +x f
  $ hg add e f
  $ hg amend -q
  $ hg up -Cq a

Write files to the working copy, and ensure they're still there after the rebase
  $ echo "abc" > a
  $ ln -s def b
  $ echo "ghi" > c
  $ echo "jkl" > d
  $ echo "mno" > e
  $ hg tglog
  o  3: f56b71190a8f 'c'

  $ hg rebase --debug -s b -d a | grep rebasing

Ensure working copy files are still there:
  $ cat a
  abc
  $ readlink.py b
  b -> def
  $ cat e
  mno

Ensure symlink and executable files were rebased properly:
  $ hg up -Cq 3
  $ readlink.py e
  e -> somefile
  $ ls -l f | cut -c -10
  -rwxr-xr-x

Rebase the working copy parent
  $ hg up -C 3
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg rebase -r 3 -d 0 --debug | grep rebasing
  rebasing in-memory

Make sure it throws error while passing --continue or --abort with --dry-run

  abort: cannot specify both --dry-run and --continue
