stop ATTN service during watchdog time out handling

A watchdog time out will initiate a dump. As a side-effect, the dump
will likely trigger a checkstop attention. We do not want ATTN to handle
this attention. So we are stopping the ATTN service before initiating
the dump. The ATTN service will be restarted on the next IPL.

Hardware Diagnostics for POWER Systems

In the event of a system fatal error reported by the internal system hardware (processor chips, memory chips, I/O chips, system memory, etc.), POWER Systems have the ability to diagnose the root cause of the failure and perform any service action needed to avoid repeated system failures.

Aditional details TBD.

Building

For a standard OpenBMC release build, you want something like:

meson -Dtests=disabled <build_dir>
ninja -C <build_dir>
ninja -C <build_dir> install

For a test / debug build, a typical configuration is:

meson -Dtests=enabled <build_dir>
ninja -C <build_dir> test
