Fix docker-sonic-vs following upgrade to Bookworm (sonic-net#21063)

FRR 10.0.1 upgrade (sonic-net#20269) brought in a mgmtd daemon for FRR. This needs to be started up in docker-sonic-vs as part of the other daemons in this container.

Additionally, Debian Bookworm provides version 2.5.0 of scapy, but the pip3 command later in the file downgraded it to 2.4.5, which does not work in Bookworm. Fix this by removing the pip3 installation for scapy, and updating the other packages installed via pip3.
