frr: fails to start due to missing frr-watchfrr package

[brianjmurrell]

It seems that I can ask an imagebuilder recipe to install frr, frr-ospfd, and frr-zebra and only those packages. However when it comes time to starting frr the following error is encountered:

Mon Feb  3 18:10:32 2025 daemon.notice procd: /etc/rc.d/S95frr: cannot start staticd: daemon binary not installed
Mon Feb  3 18:10:32 2025 daemon.notice procd: /etc/rc.d/S95frr: Starting watchfrr with command: '  /usr/sbin/watchfrr  -d  -F traditional   zebra mgmtd'
Mon Feb  3 18:10:32 2025 daemon.notice procd: /etc/rc.d/S95frr: /etc/rc.common: eval: line 220: /usr/sbin/watchfrr: not found

Clearly frr-watchfrr is a prerequisite here and should be installed. But the user should not have to know and specify this. Rather, one of the packages I requested be installed, frr, frr-ospfd, and frr-zebra should have a dependency on frr-watchfrr if it's needed to start up frr.
