realpath: Bring back GNU extension on ENOENT and EACCES [BZ #28996]
The GNU extension for realpath states that if the path resolution fails with ENOENT or EACCES and the resolved buffer is non-NULL, it will contain part of the path that failed resolution. commit 949ad78a189194048df8a253bb31d1d11d919044 broke this when it omitted the copy on failure. Bring it back partially to continue supporting this GNU extension. Resolves: BZ #28996 Signed-off-by: Siddhesh Poyarekar <siddhesh@sourceware.org> Reviewed-by: Andreas Schwab <schwab@linux-m68k.org>
