[PATCH v2] configure.ac: add subdir-objects

This allows to avoid the following warning when re-generating the configure script: auparse/Makefile.am:95: warning: source file '../lib/gen_tables.c' is in a subdirectory, auparse/Makefile.am:95: but option 'subdir-objects' is disabled To make this possible and avoid a bug in automake < 1.16, we have to adjust two Makefile.am, to use a relative path rather in _SOURCES rather than a path that uses $(top_srcdir). Indeed, $(top_srcdir) was not properly expanded when used in _SOURCES in automake versions < 1.16.
