Check for deprecated automake configure.in (wishlist #708482)

[Gautier Minster <gautier+debian@minster.io>]

Hello,

I wrote a lintian check for wishlist item #708482, which simply checks
for an Automake Makefile.am and a deprecated configure.in in source
packages.

Since this is my first lintian check, I'm pretty sure it's far from
perfect, so I would be grateful if you could give me some feedback!

Best regards,
