[PATCH 1/4] readline: improve aclocal.m4 handling

[Ross Burton <ross.burton@arm.com>]

I don't know why I decided to copy aclocal.m4 to acinclude.m4 to avoid
autotools.bbclass deleting the upstream hand-maintained aclocal.m4, but
I did.

A neater fix is to exclude aclocal, which has the side-effect of not
deleting aclocal.m4 in do_configure.
