Change gnulib-tool to support NetBSD's join

For backwards compatibility, the 4.4BSD join used by NetBSD supports a
"-a" option as if it was "-a 1 -a 2".  Unfortunately, this was done in
such a way that "-a 1" and "-a 2" need to be passed as "-a1" or "-a2".

+	* gnulib-tool: change "join -a 2" to "join -a2", the latter is
+	required by the NetBSD (and perhaps other 4.4BSD derived) join.
