[Debian-med-packaging] Removing libgmap1 binary package

[Alex Mestiashvili]

Hi,

I am about to drop libgmap1{,-dev} binary packages with 0 reverse
dependencies.
Library was introduced in version 2017-05-08 of gmap, but in the never
versions support is optional and by default library is not built.

Is there anything I should consider before uploading the new version of
gmap without libgmap1{,-dev) ?

Thank you,
Alex
