chore(linux): Address comments from Debian mailing list

The upload of the beta version caused some comments on the [Debian Input
Method](https://lists.debian.org/debian-input-method/2024/02/msg00062.html)
mailing list. This change addresses these:

- rename libkeymancore package to include SONAME: libkeymancore1
- remove unnecessary dependency on quilt

Additionally this change sorts the build dependencies alphabetically.
