autogen.sh: Check for autoconf/automake wrapper scripts

Browse Source 
For example OpenBSD uses a "autoconf" and "automake" wrapper script which
tells the user to set AUTOCONF_VERSION and AUTOMAKE_VERSION environment
variables. This patch enhances autogen.sh to not detect these wrapper
scripts as regular autoconf/automake commands but to set the required
environment variables after detecting the real "command-X.Y" commands.

Tested on OpenBSD 5.1.
