Add mavlink-router package to fpv profile

[widgetii]

Please consider adding mavlink router to fpv profile.

This software uses Meson+Ninja build system (can be installed on build machine by sudo apt install git meson ninja-build

Then use build instructions, adjusted for cross-compilation (as example of EV300 system):

meson setup -Dsystemdsystemunitdir=/usr/lib/systemd/system --buildtype=release --cross-file meson-cross-arm-openipc-linux-musleabi.ini  build .
meson compile -C build

Target binary for IPC will be located at ./build/src/mavlink-routerd. Make sure that libstdc++.so.6 dependency is also copied to the target. Consumed size data:

280656   mavlink-routerd
1490244  libstdc++.so.6

meson-cross-arm-openipc-linux-musleabi.ini.zip

Previous recipe required libstdc++ as dependency and will take of 1729Kb of space. If there is no other application in the system which require libstdc++ one can build mavlink-routerd with static-linked libstc++
