build: ship autobuild.m4, to reduce bootstrap requirement

Browse Source 
Shipping a copy of autobuild.m4 makes it so that users need not
pre-install autobuild just for aclocal to find the macro AB_INIT.

* libltdl/m4/.gitignore: Drop autobuild.m4.
* libltdl/m4/autobuild.m4: New file, copied from autobuild.
* configure.ac (AB_INIT): Unconditionally call it.
