ash: sync up with dash with respect to redirection escaping

We fixed the problem differently than they. Let's not deviate.

Upstream commit:

    Date: Thu, 27 May 2010 20:07:29 +1000
    [EXPAND] Fix corruption of redirections with byte 0x81

    In other ash variants, a partial implementation of ksh-like cmd >file*
    adds and removes CTLESC bytes ('\x81') in redirection filenames,
    preserving 8-bit transparency. Long ago, dash removed the code to add
    the CTLESC bytes, but not the code to remove them, causing corruption of
    filenames containing CTLESC. This commit removes the code to remove the
    CTLESC bytes.

    The CTLESC byte occurs frequently in UTF-8 encoded non-Latin text.

    This bug has been reported various times to Ubuntu and Debian (e.g.
    Launchpad Ubuntu #422298). This patch is the same as the one submitted
    by Alexander Korolkov in Ubuntu #422298.
