Fix 'svn patch' setting UNIX permissions to 0600 on patched files with props.
(init_patch_target): Use the working copy's own temp directory to store
temporary files for patching, instead of using the system-wide temp dir.
With a system-wide dir, permission paranoia in svn_io_open_unique_file3()
may kick in and result in patched files with permissions not matching the
umask. Generally, any temp files that may end up as user-visible files
in the working copy should be created in the working copy's temp dir.
