mail/mailsync: Fix build with Clang 6.0.0

exit function declared in autoconf 2.59 configure scripts conflicts
with Clang 6 because stdlib.h declares it with an attribute for C++11
or later. This is fixed in later versions of autoconf 2.60.

- Add USES=autoreconf to regenerate configure, new version of
  autoconf no longer declares the exit function. [1]
- Merge the changes from files/patch-configure and post-patch taget
  into acinclude/ac_with_{cclient,openssl}.m4
