gnome-user-share: Improve packaging quality

[Artur Rona]

Dear maintainers,

I noticed some packaging issues in gnome-user-share.

- debian/control: for B-D libselinux1-dev and libgnome-bluetooth-dev
more better way is [!linux-any] than [linux-any]

- Upgrade to source format quilt 3.0.

- Upgrade Standards-Version to latest and upgrade to new upstream
release 2.30.2

I look forward to your response,

Best Regards,
Artur Rona
