build: handle directory with whitespace in AUTOREMOVE clean

Package with whitespace in their build directory are not correctly
removed when CONFIG_AUTOREMOVE is enabled. This is caused by xargs that
use whitespace as delimiters. To handle this use \0 as the delimiter and
set find to use \0 as the delimiter.
