Include libgirepository1.0-dev as a dependency

[atoft]

I have to install this manually to get it to build on Debian.

Huh. I thought it was a dependency of libglib2.0-dev, which is required by valac...

[bleakgrey]

This should apply for Debian too. Are you sure this library wasn't removed on accident on your system?

[atoft]

It's a fresh install of the latest Mobian build (which is Debian Bullseye), on which I ran sudo apt install meson valac libgtk-3-dev libsoup2.4-dev libgranite-dev libjson-glib-dev.

I'm a newbie when it comes to this stuff but I used apt-rdepends (which I think is the right commandline equivalent?) and it doesn't show a dependency between libglib2.0-dev and libgirepository1.0-dev.
The only connection is:
Suggests: libgirepository1.0-dev (>= 1.62)

I wondered why it showed up all of the sudden and it took me a distro switch yesterday to realize that libhandy depends on this package.
