Avoid mapping ENOENT to ENOTDIR for non-existent path components.

Browse source 
The ENOTDIR mapping was introduced in r235266 for kern/128933 based on
an interpretation of the somewhat ambiguous language in the POSIX realpath
specification.  The interpretation is inconsistent with Solaris and Linux,
a regression from 9.0, and does not appear to be permitted by the
description of ENOTDIR:

     20 ENOTDIR Not a directory.  A component of the specified pathname
             existed, but it was not a directory, when a directory was
             expected.
