meson: refactor generators

Using 'run_command' is not the appropriate way to generate code
since it only runs when meson itself runs and doesn't expose to
meson the correct dependency information.  'custom_target' is
the more appropriate way to generate code, so switch to using it.

This was noticed because when trying to build as a subproject, the
depending repository failed with:
```
subprojects/phosphor-host-ipmid/meson.build:229:0: ERROR: Sandbox
violation: Tried to grab file sensor-gen.cpp outside current
(sub)project.
```
