GNS3 and dynamips updates

Upgrade gns3-gui.

- I tested Alpine Linux docker container on aarch64 as well.

#### Local build testing
- I built this PR locally for my native architecture, (x86_64-GLIBC)
- I built this PR locally for these architectures (if supported. mark crossbuilds):
  - aarch64
  - aarch64 (crossbuild)
