fix: set correct metadata for debian packages

[mattdibi]

Currently, in our .deb packages, we're not setting the metadata correctly.

Architecture

Reference: https://www.debian.org/doc/debian-policy/ch-controlfields.html#architecture

Depending on context and the control file used, the Architecture field can include the following sets of values:

• A unique single word identifying a Debian machine architecture as described in Architecture specification strings.
• An architecture wildcard identifying a set of Debian machine architectures, see Architecture wildcards. any matches all Debian machine architectures and is the most frequently used.
• all, which indicates an architecture-independent package.
• source, which indicates a source package.

We're currently using all but it's not correct since we have architecture dependent code. I updated the Architecture fields using the "Architecture specification strings" as per Debian documentation.

Description

Reference: https://www.debian.org/doc/debian-policy/ch-controlfields.html#description

In a source template control file or binary control file, the Description field contains a description of the binary package, consisting of two parts, the synopsis or the short description, and the long description. It is a multiline field with the following format:

Description: single line synopsis
extended description over several lines

I added the "single line synopsis" in this PR.
