aclocal.m4: Fix compatibility with upcoming autoconf-2.70.

Under autoconf 2.69c (beta) `./configure` fails as: ``` ./configure ... checking for msgfmt... msgfmt ./configure: line 7441: syntax error near unexpected token `newline' ./configure: line 7441: ` ''' ``` This happens due to underquoting of a snippet argument for `AS_VAR_SET_IF` call.
