dh-autoreconf: aclocal: rename aclocal.m4 to acinclude.m4

[Jerome BENOIT <g6299304p@rezozer.net>]

Hello Forum,

aclocal rewrite the aclocal.m4 files, so precious information can be lost:
a workaround is to rename the `aclocal.m4' files `acinclude.m4'.

When this renaming process can take place ? in d/rules ? at the repacking stage ?

Thanks in advance,
Jerome
